Showing 12 in progress, 89 upcoming and 74 past of 175 events
In-progress, upcoming, and past groupings use listed dates and recorded outcomes as of October 25, 2026. For a backyard race without a recorded finish, a seven-day display window is a calendar estimate, not confirmation that the race is still running. Directory records were reviewed against the linked official sources during reviews dated June 22, 2026 – October 23, 2026. A future start date does not mean registration is open. Dates, entry rules, availability, fees, and course details can change; verify them with the organizer before registering or booking travel. “Simpler logistics” is an editorial comparison, not a safety rating.
Listed dates overlap today. Check the organizer for live status.

Edition note: The published UltraSignup entry deadline was Thursday, October 22, 2026 at 11:59 PM Pacific Time and has passed. The free T-shirt was guaranteed only for entries made by October 12. The organizer's event page still carries 2025 dates in its title, but its race calendar and UltraSignup give October 23–25, 2026.
Brugg, Aargau, Switzerland
A 48-hour race with 24-, 12- and 6-hour options on a lit, fully paved 934.8 m loop on the Aare island at Geissenschachen in Brugg, doubling as the Swiss 48-, 24- and 6-hour championships.
Edition note: The 19th edition. Regular entry closed October 14 and online entry closed October 22, 2026. The organizer advertises on-site entry after that with a CHF 20 late fee; availability must be checked for the selected race. On October 12 the RaceResult list showed 36 runners in the 48-hour race and 26 in the 24-hour race. No separate 2026 live results link was verified in this review.

A 145 km night-start trail race from the Sassi of Matera to the beach at Castellaneta Marina through Puglia’s Gravine canyons, with 3,500 m of climbing and a 27-hour limit.
Edition note: Registration is closed on the official race page checked October 23, 2026. The organizer offers no waiting list or reopening. Bib-collection slots and runner shuttles had to be booked by October 14. Distance figures differ by source: the race page gives 145 km and 3,500 m+, its course table 142.5 km with 3,492 m+ and 3,875 m−, and UTMB Live 144 km with 3,800 m+. Some third-party calendars list November 6, 2026; UTMB’s official dates are October 23–25.

Edition note: The 10th edition. Online entry was open on October 12, when 20 runners were on the 24-hour entry list. The published fees were 1,300 CZK for the 24-hour, 12-hour or 100 km race and 520 CZK for the marathon; the October 20 bank-transfer deadline has passed. Confirm any late entry directly with the organizer. A dedicated 2026 live-results page has not been verified here.
Veszprém, Hungary
A 24-hour race on a closed synthetic stadium track in Veszprém, held with 12- and 6-hour races and doubling as the Hungarian 24-hour championship. It is part of the Central-European Ultra Series (CEUS).
Edition note: On October 12 the organizer’s entry page listed the 24-hour individual race as closed except for Hungarian championship entries; the 12-hour race was still open at 30,000 HUF. The information pack checked on October 22 gives revised lap lengths and field limits; see below. The organizer promises live coverage and online results, but no 2026 live results page was published on October 12.
New River Gorge, West Virginia, USA
A 100-mile out-and-back through New River Gorge with repeated rim-to-river traverses, 12,000 ft of climbing, and a 32-hour cutoff.
Edition note: The previously published October 17 entry deadline has passed, but UltraSignup still displays sold-out and waitlist wording on October 22; confirm availability directly. The organizer’s linked 2026 information pack still routes miles 14–20 over the Rend Trail near Thurmond. NPS continues to report a full closure from August 3, 2026 until an estimated fall/winter 2027 reopening. No replacement route was verified in the reviewed sources on October 22.
A&P Showgrounds, Waipukurau, Central Hawke’s Bay, New Zealand
A free-entry backyard ultra at the Waipukurau A&P Showgrounds in Central Hawke’s Bay, on a flat 6.7 km loop of limestone paths and singletrack beside the Tukituki River.
Edition note: The fourth edition starts at 9:00 AM on Saturday, October 24, 2026, over Labour Weekend. The published Webscorer deadline was 8:59 PM NZDT on October 21. On October 22 the organizer’s homepage still advertised registration open, but current entry availability could not be verified. Entry is free; on October 20 Webscorer showed 307 registrations across the backyard and the Kids Classic. Big’s Backyard Ultra lists a capacity of 250. Big’s race listing still gives the record as 37 yards (Fiona Hayvice, 2024); the council’s 2025 race report and Yardlore show Glenn Tomlinson won the 2025 edition with 43 yards, so 43 is the current course record. The organizer’s rules page is still dated for the 2024 race.
Port Angeles, Washington, USA
A scenic 24-hour endurance race at Salt Creek Recreation Area on the Olympic Peninsula, on a 1.4-mile loop of paved and unpaved surfaces. Also offers a 12-hour solo race, 24-hour relay teams and an hourly Last Runner Standing up Striped Peak.
Edition note: At the October 23, 2026 check, RunSignup displayed entry links and fees of $35–$99 for 24 hours, $35–$89 for 12 hours, $35–$79 for relay entries and $99 for Last Runner Standing, depending on entry category. Racing starts at 8:30 AM or 9:00 AM on October 24. The separately listed pacer-bib deadline is October 24 at 11:59 PM; it is not a race-start deadline.
Smithfield, Cairns, Australia
A Cairns backyard ultra on the trails of Smithfield Mountain Bike Park, with hourly starts and a separate six-lap introductory event.
Edition note: Online registration closed on October 22, 2026; Race Roster confirms it is closed as of October 23. The backyard and the six-lap Mini Backyard share a cap of 250 entries. The organizer's pages give the climb per lap as about 95 m on the event page and about 125 m on the course page.
Laya, Gasa, to Bumthang, Bhutan
A five-day stage race for selected, invited runners along Bhutan's Snowman Trek, from Laya in Gasa to Bumthang, covering about 185 km with passes up to 5,470 m to draw attention to climate change.
Edition note: This is the third international edition. It starts in Laya on October 24, the second day of the Royal Highland Festival, and is scheduled to finish in Bumthang on October 28. The updated 2026 segment list names Wangduechhoeling Palace Ground, while an older paragraph still names Chamkhar Sports Arena; confirm the precise finish venue in the final briefing. There is no open registration: prospective runners contact the race director. On October 12, the organizer's athletes page listed 18 runners, 12 international and 6 from Bhutan.
Future editions. Use the official website to check whether entries are open.
Maneybhanjang, near Darjeeling, India
A five-stage, 100-mile race from Maneybhanjang near Darjeeling up the India–Nepal border ridge to Sandakphu at 11,815 ft, with Everest views and supported daily stages.
Edition note: ITRA lists 2026 as the 35th edition. The five race stages run October 29 to November 2, 2026, inside an eight-day package that starts at Bagdogra airport on October 27 and ends there on November 3. The package costs USD 1,998 per person in a shared room, plus USD 470 for a single room. A non-refundable USD 625 deposit holds a place, and the balance was due by August 31, 2026. The organizer’s FAQ gives September 15 as the last date for registration, so contact the organizer before planning a late entry. ITRA lists the course as 153.36 km with 7,009 m of climbing and a 50-hour limit. The organizer’s stage distances add up to 100.4 miles, and its stage climbs add up to 5,973 m.
Saint-Laurent-du-Pont, Isère, France
A flat backyard ultra in Saint-Laurent-du-Pont, with 6.706 km out-and-back yards along the Guiers river, a gymnasium base camp and the first yard at noon on Friday.
Edition note: Registration for 2026 is full, with a waiting list on njuko at €79. The organizer’s French pages carry the 2026 date; the English pages still describe the 2022 edition. The organizer’s home page still calls the race a Silver Ticket event and quotes a 308 km Chartreuse record, which is Christian Mauduit’s 46 yards from 2020. Big’s race page labels the 2026 race Bronze, and the organizer’s own 2022 results show 56 yards (375.536 km). The rules give 6.704 km per yard; the race information page and Big’s say 6.706 km. Yards completed here count toward Big’s At-Large list, which takes the best results between August 16, 2025 and August 15, 2027.
Höganäs to Båstad, Sweden
A 173 km coastal point-to-point through southern Sweden with technical nature-reserve trails, long darkness, and a 32-hour cutoff.
Edition note: The 100-mile race is sold out. The race page checked October 23 lists 2,020 m of climbing. The official schedule gives the last finish as 2:00 AM on Sunday, November 1, after the Friday 6:00 PM start; the October 30–31 festival banner does not cover the full race window.
Estellencs to Port de Sóller, Mallorca, Spain
A 138 km night-start mountain race across Mallorca’s Serra de Tramuntana from Cala Estellencs to Port de Sóller, with 5,350 m of climbing on cobbled paths and forest trails.
Edition note: Race full. UTMB’s race list showed all four Mallorca by UTMB races sold out on October 20, 2026. Sources differ on the course: the race page gives 138 km, 5,350 m+ and a 30:30 limit (finish closing 4:30 AM Sunday), while the 2026 regulations say about 137 km, about 5,200 m+ and 30 hours, and Western States lists 135 km. The course table on the race page still carries 2025 dates; its times of day match the 2026 schedule. The organizer may change or shorten routes for weather warnings or trail conditions.
McDowell Mountain Regional Park, Arizona, USA
A social desert-trail 100 using five rolling loops in McDowell Mountain Regional Park, with an estimated 6,296 ft of gain and a 30-hour cutoff.
Edition note: The organizer still links a waitlist, while its text says registration closed October 1 and UltraSignup displays an October 30 opening time. It is unclear whether regular entry will reopen, so confirm any late entry with Aravaipa.
Wadi Rum, Jordan
A three-stage, food-self-sufficient desert race in Jordan’s Wadi Rum, with 70, 100 or 120 km options, three nights at a fixed bivouac and a 3.5 km/h minimum speed.
Edition note: The 6th edition runs October 31 to November 7, 2026, with stages on November 2, 3 and 5 and a rest day on November 4. On October 20 the organizer’s page marked both Hilton packages (€2,700) as completed; the Crowne Plaza package (€2,550) carried no such label. Refunds ended on August 9 and deferrals on September 20, 2026. In a September 8 update the organizer said recent low-cost airline cancellations to Jordan were commercial decisions, and that the Jordan Tourism Board had confirmed normal conditions for visitors. LiveTrail had no 2026 page yet on October 20.
Mark Twain National Forest to Steelville, Missouri, USA
An approximately 101-mile point-to-point race through Missouri's Mark Twain National Forest, using mostly Ozark Trail singletrack with a 32-hour cutoff.
Madeira, Portugal
A mountainous two-stage race across Madeira, with a 110 km continuous option and shorter single-day races on the same weekend.
Edition note: The 2026 edition is sold out. The current runner guide describes the advertised 110 km category as approximately 113 km with 7,765 m of climbing, but its cutoff table ends at 117.5 km. Confirm the final GPX and briefing rather than assuming those distance figures are interchangeable.
Guangyuan, Sichuan, China
The 104 km DSD 100K at Ultra-Trail Shudao by UTMB follows the ancient Shu Roads of Guangyuan, Sichuan, past Jianmen Pass to Zhaohua Ancient Town, with 3,800 m of climbing and a 26-hour limit.
Edition note: Registration is closed for all four races (checked October 20, 2026), although the registration page still carries a “Registration OPEN – 2026” line. The DSD 100K starts at 9:00 PM on Friday, November 6, at Dashudao Buye Sanguo Town and must reach Zhaohua Ancient Town by 11:00 PM Saturday. The race header gives 104 km and 3,800 m, but the official aid-station table ends at 97.1 km with 3,709 m of climbing, and the course text still names Jiange Stadium as the start. UTMB Live listed the event as “coming soon” on October 20; its 2026 tracking page was not yet published.
Butler Green, Arrowtown, Otago, New Zealand
A backyard ultra based on Butler Green in Arrowtown, near Queenstown, on a 6.71 km loop of hard-packed trail and bush singletrack along Bush Creek and the Arrow River.
Edition note: The fourth edition starts at 9:00 AM on Saturday, November 7, 2026. Entry is $220 through Webscorer, plus a 3% surcharge for card payments. On October 20 Webscorer showed 151 registrations and said the event was 94% full; registration closes at 11:59 PM NZDT on Friday, November 6. Big’s Backyard Ultra lists a capacity of 150 and says the race sold out in 2023, 2024 and 2025. Big’s race page labels it “Bronze”.
Stephen F. Austin State Park, San Felipe, Texas, USA
A last-runner-standing backyard ultra at Stephen F. Austin State Park in San Felipe, west of Houston, with a 4.167-mile crushed-gravel yard every hour until one runner is left.
Edition note: The fourth edition. Registration is open on RunSignup, which showed 18 of 196 Last Runner Standing places left on October 20. The separate Last Rucker Standing division has been folded into the main race: ruckers may still ruck, but there is no separate course or division this year. Big's race page lists the category as "Bronze". The organizer's site says TROT "has applied for a 2026 Bronze Coin and 2027 Silver Ticket", while its RunSignup page calls 2026 "a Bronze Ticket race". The organizer says live tracking will be posted but has not published the link yet. The TROT page calls 2026 both the "fourth year" and "year three"; RunSignup says year four, which matches results from 2023, 2024 and 2025.
Pine Glen Campground to Sylacauga, Alabama, USA
A point-to-point Alabama 100-miler through Talladega National Forest and the Pinhoti Trail, ending near Sylacauga with a 32-hour cutoff.
Edition note: UltraSignup now marks registration closed on October 21, 2026 at 11:59 PM, later than the previously listed October 17 deadline. Bib pickup and drop-bag handover are Friday, November 6, 3:00–7:00 PM; there is no Saturday packet pickup or race-day registration.
Beal's Point, Granite Bay, California, USA
A varied Northern California 100-miler combining Folsom-area loops with an out-and-back trail journey into the Sierra foothills and a 30-hour cutoff.
Edition note: The organizer advertises registration through November 2. The final 2026 runner guide is still marked coming soon as of October 15; use the current 2026 schedule and pace chart while awaiting it.
Ultima Basecamp, Queen Maud Land, Antarctica
A fly-in Antarctic ultra on a 4.2 km out-and-back snow course at Ultima Basecamp in Queen Maud Land, with 50 km to 100-mile races, a 24-hour race and a 24-hour limit.
Edition note: The third edition. Runbuk’s provisional schedule has a mandatory briefing and gear check in Cape Town on November 5, the flight to Ultima Basecamp on November 7, the race on November 8 and the flight back to Cape Town on November 12. Every flight depends on the weather, and the organizer advises keeping at least two weeks free after the planned return. The 2026 entry fee is USD 19,500 (USD 18,500 per person for a team), paid in full at registration, and places are limited by aircraft capacity. The 2026 competitor list showed 31 names on October 20, 2026. The start time has not been published; the end date here allows for the 24-hour limit running into November 9.
Inglis to St. Augustine Beach, Florida, USA
A 200-mile coast-to-coast trail race across Florida from the Gulf end of the Withlacoochee Bay Trail to St. Augustine Beach, with 110 miles on the Florida Trail and a 96-hour limit.
Edition note: Registration is open on UltraSignup until 11:59 PM ET on Friday, November 6, 2026; on October 20 it showed 57 entrants and 3 spots left. UltraSignup and DUV list the event as November 10–15 because packet pickup opens on November 10, but the race starts at 10:00 AM on Wednesday, November 11. The organizer’s 2026 guidebook (updated October 14) differs from its race page and UltraSignup on some points: pacers from Aid Station 5 (guidebook) or 6 (race page), entry transfers until 14 or 7 days before the race, deferral credit or no refunds, and a finish at the end of Pope Road or at the St. Johns County Ocean & Fishing Pier. This record follows the guidebook. The live tracking link had not been published on October 20.
Solukhumbu, Nepal
A six-stage, 170 km Himalayan race in Nepal's Solukhumbu region, reaching 4,104 m with 26,000 m of total ascent and descent.
Antarctica
The final event in the 4 Deserts Grand Slam. A multi-stage footrace on the Antarctic continent, accessed by expedition ship from Ushuaia, Argentina. Stages depend on Antarctic landing and weather conditions.
Edition note: November 13–23 is the full expedition window, including the voyage from and back to Ushuaia. The current itinerary places up to six Antarctic stages between November 16 and 20, subject to landing and weather conditions.
Mui Wo, Lantau Island, Hong Kong
A 104 km night-start loop from Mui Wo across the ridges, coast and villages of Hong Kong’s Lantau Island via Tai O and Ngong Ping, with 4,500 m of climbing and a 27-hour limit.
Edition note: TransLantau100 registration was still open on October 20, 2026; the TL50, TL25 and TL15 are sold out. Transfers to another runner closed four weeks before bib distribution opens on November 6. The race header gives 104 km and 4,500 m+, the official aid-station table 102.8 km and 4,640 m, and the event concept page 103 km. UTMB Live listed TransLantau as “coming soon” on October 20; its 2026 tracking page was not yet published.
Tandur, Queensland, Australia
A Queensland backyard ultra at Cobb & Co Nine Mile Camping Grounds, with a campsite base for runners and crews between hourly loops.
Vienna, Illinois, USA
A flat, fast 100-mile rail-trail race on crushed limestone with a maximum grade of about 2% and a record-focused reputation.
Edition note: Online registration closes October 30 at 11:59 PM Central Time. The 100-mile race starts November 14 at 7:00 AM and has a 30-hour limit, finishing by 1:00 PM Sunday. The USATF national championship is the separate 50-mile race.
Ouarzazate, Morocco
A two-day, 110 km desert ultra around Ouarzazate, with shorter 50 km and 25 km options on rocky trails and oasis terrain.
Edition note: The organizer lists the November 14–15, 2026 edition as sold out as of October 23. The interest form is for 2027; it is not a confirmed 2027 entry.
Namib Desert, Namibia
A 250km self-sufficient desert ultramarathon across five stages in the Namib Desert, with sand dunes, scrubland, heat, and tented camps.
Athens to Sparta and back, Greece
A 485.3 km non-stop road race from the Ancient Agora of Athens to the statue of Leonidas in Sparta and back, with a 98-hour limit and a 524.9 km option that finishes in Marathon.
Edition note: Applications closed on September 30, 2026, and the organizer’s registration page now says registration is closed. The live tracking link will be announced before the race. The organizer gives 485.3 km for the 2026 route, while DUV lists every past edition as 490 km and the regulations are still headed “Athens – Sparta – Athens 490 km”. The 93-hour cutoff at the Ancient Agora in the regulations applies only to runners continuing to Marathon; the Athens–Sparta–Athens limit is 98 hours.
Villa Carlos Paz, Córdoba, Argentina
An inaugural night-start backyard ultra on Villa Carlos Paz's lakeside costanera, repeating a flat 6.706 km loop every hour.
San Carlos de Bariloche, Patagonia, Argentina
The Tronador 130K of Patagonia Bariloche by UTMB loops from Bariloche’s Centro Cívico over Cerro Otto, Catedral and Bella Vista, with 6,580 m of climbing and a 33.5-hour limit.
Edition note: Race full. UTMB’s race list showed all six races sold out on October 20, 2026, and the organizer allows no refunds or transfers. The event runs November 18–22 with check-in on November 18, 19 and 20; the Tronador starts at 9:00 PM Friday, November 20. The medical certificate and declaration of honor must be uploaded to MyUTMB before October 25. The organizer sends GPX files the week before the race, and the course table on the race page still mixes 2025 and 2026 dates. UTMB Live had not opened a 2026 page by October 20.
Twofold Bay to Charlotte Pass, New South Wales, Australia
An invitational 240 km journey from the Tasman Sea to Australia's highest mountain, finishing at Charlotte Pass after summiting Kosciuszko.
Chuí to Cassino, Rio Grande do Sul, Brazil
A non-stop 226 km crossing of Brazil's immense southern beach from Chuí to Cassino, with about 130 m of climb and a 52-hour limit. The low elevation gain does not remove the challenges of sand, exposure and self-sufficiency between bases.
Goodyear, Arizona, USA
A fixed-time festival on a certified 0.988178-mile concrete loop, headlined by the 48-hour race and 2026 USATF 24-Hour Championships.
Edition note: Online registration closes November 16 at 11:59 PM Mountain Time. The 48-hour race starts November 20 at 8:00 AM; the USATF 24-Hour Championship starts November 21 at 8:00 AM. The organizer also lists race-day registration from 7:00 AM.
Cape Town, South Africa
Cape Town’s 100-mile trail race loops from Gardens Rugby Club over Table Mountain and down the Cape Peninsula to Simon’s Town and back, with over 7,000 m of climbing and a 45-hour cutoff.
Edition note: On October 8, 2026, IOL reported that the shorter races had sold out but places remained in the 100-miler and the UT100; the organizer’s site does not show live entry status. Entrants who have not yet submitted a qualifying result must email it by midday on October 28, the same deadline for substitutions and changes of distance. Sources differ on the course: the race page gives 163 km with 7,187 m D+ in its stats and 7,516 m in its text, and the organizer’s October 14 timing schedule gives 162.11 km and 7,242 m. The organizer had not posted a 2026 live-tracking link by October 20.
Takao Green Center, Hachioji, Tokyo, Japan
The Tokyo race of Japan’s Last Samurai Standing backyard ultra series: 6.706 km yards on a forest road from Takao Green Center in Hachioji, with 28 places.
Edition note: This is the backyard running race, not the 2025 Netflix drama of the same English title. The organizer’s 2026 schedule lists Tokyo as a Bronze race with general entry; the published entry window ran from July 18 to 11:59 PM Japan time on October 20, 2026 and has closed. The page lists a minimum of 20 runners but also says it will cancel with 20 or fewer; confirm the race’s go-ahead with the organizer. Big’s race page also lists November 21, 2026 at 13:00 and labels the race Bronze, but it still shows a 54-yard course record from 2020 and a 30-runner capacity. Yardlore lists the 2026 edition on November 1. Yards completed here count toward Big’s At-Large list, which takes the best results between August 16, 2025 and August 15, 2027.
Bislett Stadium, Oslo, Norway
A 24-hour race on the 546.5 m indoor track under the stands of Bislett Stadium in Oslo, with an official 100-mile split, a lottery for 150 places and a 165-runner cap.
Edition note: Sold out. Registration for the 2026 lottery ran from May 1 to May 4 and the draw was on May 5: 683 runners applied for 150 places, and the field is capped at 165. The only way in now is to buy a place from an entrant through the organizer’s resale procedure, open until November 15 with a NOK 400 transfer fee. The organizer lists an IAU Bronze Label, but the IAU calendar entry for 2026 shows no label. The 2026 participant information had not been published on October 20, so the race-day rules below come from the 2025 edition.
Dinosaur Valley State Park, Glen Rose, Texas, USA
A looped Texas trail 100 in Dinosaur Valley State Park with roughly 9,000 ft of climbing and mandatory progressive cutoffs across the repeated-loop course.
Edition note: The November 21–22, 2026 edition starts at 07:00 on Saturday. UltraSignup closes online entry November 18 at 23:59 Central Time. The organizer publishes intermediate cutoffs rather than one standalone finish limit; see the 2026 schedule below.
Boonsboro to Williamsport, Maryland, USA
America's oldest ultramarathon, first run in 1963: 50.2 miles from Boonsboro to Williamsport, Maryland, over the Appalachian Trail and C&O Canal towpath, with a 13-hour limit.
Edition note: Registration sold out. RunSignUp says registration opened at midnight on March 1, 2026, and the organizer says it sold out in record time. Entries cannot be refunded, transferred or deferred. Packets are collected Thursday or Friday in Hagerstown, because no race numbers are handed out on race morning. Live GPS tracking runs through the RaceJoy app linked from RunSignUp.
Marble Falls, Texas, USA
A Thanksgiving-week backyard ultra in Marble Falls, Texas, now run by Perspective Pacing, with a roughly 4.17-mile yard every hour and a 68-yard course record set by Mark Dowdle in 2025.
Edition note: The sixth edition and the first under Perspective Pacing, which took over from Summit Trail Racing. Registration is open on RunSignup at $150 through October 23, then $175 until it closes at 11:59 AM on November 14; shirts are guaranteed only for entries by October 30. Start time: the organizer's race-day schedule (packet pickup 6:00 to 7:30 AM, briefing 7:30 to 7:45 AM, start 8:00 AM, no late starts) conflicts with the 7:00 AM event time on RunSignup. This page uses 8:00 AM, the time on the organizer's schedule and of every previous edition. RunSignup's November 21 to 26 date range is a booking window, not a set finish. The 2025 race was billed as a "2026 Silver Ticket Race". For 2026, neither the organizer nor Big's race page, which still shows the 2025 listing, gives a ticket level.
Snowy Mountains, New South Wales, Australia
A 160.5 km point-to-point through Australia’s Snowy Mountains with 4,731 m of climbing, a Mount Kosciuszko summit, and a 36-hour cutoff.
Edition note: The official 2026 race page now lists 160.5 km and 4,731 m of climbing. Entries are sold out. The November 27 start at 3:00 AM and 36-hour limit remain unchanged.
Saint-Étienne to Lyon, France
A night race of about 80 km from Saint-Étienne to Lyon over the Monts du Lyonnais, first held in 1952, on 65% trail and 35% road with at least 2,000 m of climbing.
Edition note: 72nd edition. On October 20, 2026 the organizer listed the SaintéLyon solo and all three relays as full, with a waiting list, while the LyonSaintéLyon still took entries. Bib transfers are possible through the runner account until November 23. The route changes every year, and the 2026 climbing figure and GPX were still marked “to come.” The race page closes Lyon at 4:00 PM Sunday, but the rules close every course at 4:30 PM. The rules call the LyonSaintéLyon 164 km; the race page says 160 km.
Chiang Dao to Chiang Mai, Chiang Mai Province, Thailand
The 173 km Chiang Dao 160 runs from Wat Tham Chiang Dao to Chiang Mai PAO Park in northern Thailand, with 9,800 m of climbing and a 48-hour limit, at the UTMB Asia-Pacific Major.
Edition note: Registration is open until 10:00 AM (GMT+7) on October 31, 2026, or until races fill, with no waiting list; transfers and distance changes also close on October 31. The festival runs over two weekends: Doi Inthanon National Park (November 27–29) and Chiang Mai PAO Park (December 3–6). The event was called Doi Inthanon Thailand by UTMB in 2022–2023, and inthanon.utmb.world now redirects to chiangmai.utmb.world. UTMB’s Majors page still describes a start and finish at Doi Inthanon National Park Headquarters, which applies to the first-weekend races, not the Chiang Dao 160. UTMB Live had no 2026 page on October 20.
Forth, Tasmania, Australia
A December backyard ultra at Forth in northern Tasmania, on a hilly 6.71 km loop of gravel and grass that starts every hour until one runner is left.
Edition note: The organizer’s Race Roster registration page gives Friday, December 4, 2026, at 9:00 AM AEDT and shows the event as full with 120 participants. Big’s Backyard Ultra’s race page instead lists December 11, 2026, at 8:00 AM and a capacity of 100; this record follows the registration page. Big’s also still lists the record as 38 yards (Ryan Crawford, 2024), while Yardlore’s 2025 results show Crawford raised it to 43. Big’s race page labels the race “Bronze”.
Pavelló Polivalent, Llagostera, Girona, Spain
A charity backyard ultra in Llagostera, near Girona, with 6.706 km yards on singletrack by day and wide tracks by night, and its start, finish and camp inside the sports hall.
Edition note: The third edition. All 225 places are taken; a free waiting list runs on The Red Cap Sports, and freed places are offered in order of sign-up. The organizer has not yet published a 2026 live results link. Its results link for 2025 points to a Wiclax page whose address says 2026 but which holds the 2025 results. Big’s race page lists daytime yards until 8:00 PM, 425 ft of climb per day loop and a start outside the pavilion; this record follows the organizer’s 2026 schedule and figures. Big’s labels the race Bronze. Yards completed here count toward Big’s At-Large list, which takes the best results between August 16, 2025 and August 15, 2027.
Brazos Bend State Park near Needville, Texas, USA
A flat, repeated-loop 100-miler in Brazos Bend State Park, built around runnable park trails and a 32-hour cutoff.
Edition note: The current navigation and cutoff page identify the 2026 race. The 100-mile limit is 32 hours, with rolling course closure beginning after the final-lap start deadline on Sunday.
Soochow University Waishuangxi Campus, Shilin District, Taipei, Taiwan
An invitational 24-hour race on the 400 m track of Soochow University’s Waishuangxi campus in Taipei, held since 1999 and certified six times as an IAU Gold Label race.
Edition note: The 2026 date comes from two calendars, not from Soochow University itself. The IAU race calendar lists the race for December 5, 2026, and the Chinese Taipei Association of Ultrarunners (CTAU) calendar lists December 5–6 on the Waishuangxi campus track, names Soochow University as organizer and marks the race as one of Taiwan’s selection races for the 2027 IAU 24H World Championships. On October 20 we found no 2026 announcement on Soochow University’s own website, and the race’s Facebook page and registration page could not be read. CTAU gave September 15 as the entry deadline, and a race-listing site shows entries closed. The IAU calendar shows no label for 2026; Soochow University reported Gold Label certification for the 2024 and 2025 races after they were run.
Hitchcock Nature Center, Honey Creek, Iowa, USA
A five-loop Iowa trail 100 at Hitchcock Nature Center, with steep repeated hills, roughly 4,928 ft of elevation change per loop, and a 34-hour cutoff.
Dorking, England, UK
Centurion Running's winter loop through southern England, starting at Juniper Hall and linking the North Downs, South Downs, and connecting trails.
Al Hamra to Birkat Al Mouz, Hajar Mountains, Oman
The 154 km Hajar Ultra crosses Oman’s Hajar Mountains from Al Hamra over Jabal Akhdar to Birkat Al Mouz, with about 8,000 m of climbing, a via ferrata near km 87 and a 48-hour limit.
Edition note: Registration for the Hajar Ultra and the 100K Jabal Classic was still open on October 20, 2026; the 50K, 30K and 20K races are sold out. There is no waiting list, and entries cannot be transferred to another runner. The organizer’s registration page gives February 9 (priority) and February 11, 2026 (general) as opening dates, while UTMB’s November 2025 announcement had said February 3 and 5. The race page lists bib collection on December 5–6 in Muscat and December 8–9 at the Race Village, 10:00 AM to 10:00 PM, but the event schedule shows 4:00 to 9:00 PM on December 5, 6 and 8, with the Muscat venue still to be confirmed. UTMB Live had no 2026 page on October 20.
Barcelona, Spain
A charity-focused 24-hour track race at Barcelona's Estadi Municipal Joan Serrahima, accompanied by 12- and 6-hour events.
Jacksonville Beach to Ponce Inlet, Florida, USA
A mostly point-to-point coastal-road 100-miler with a 7-mile opening out-and-back, a Ponce Inlet finish, and a 31-hour net-time limit.
Natural Bridge Station to Fincastle, Virginia, USA
David Horton's December night race in Virginia's Blue Ridge, billed as 100K++ but 66.6 miles on the Glenwood Horse Trail, starting at 12:01 AM with an 18-hour limit.
Edition note: Entry is by mailed application. The 2026 application says about 100 runners would be picked on October 14 from the applications received by then, with the rest chosen on October 30 and no waiting list. The organizer's site showed no 2026 entrant list on October 20. The application gives the fee as $270 if received by November 5 and $300 after, but its entry form says $300 after November 3. A 2026 live-tracking link has not been verified here.
Amecameca, State of Mexico, Mexico
A backyard ultra in Amecameca, State of Mexico, a town at about 2,480 m, where runners repeat one 6.706 km loop every hour; the first edition in 2025 ended at 47 yards.
Edition note: The second edition. Big’s race page lists December 19, 2026 at 08:00 with room for 150 runners, and Yardlore lists the same date. The organizer, Trail SIC, uses a Facebook page; an entry page, price, exact venue and full rules were not verified in the sources checked. Yardlore’s 2025 results leave out the 47-yard winner and show 46 as the best; DUV and Big’s both give 47. Big’s labels the race Bronze. Yards completed here count toward Big’s At-Large list, which takes the best results between August 16, 2025 and August 15, 2027.
Phoenix, Arizona, USA
An elite invitation-only 24-hour and 100-mile track race at Camelback High School. Entry is selective and based on qualifying standards. Organized by Aravaipa Running.
Edition note: At the October 23, 2026 check, the organizer confirmed December 19–20 at Camelback High School. Its field limits conflict: 25 runners in the overview and 30 in the entry standards. Confirm capacity when applying.
Miami Marine Stadium, Virginia Key, Miami, Florida, USA
An open-ended backyard ultra at Miami Marine Stadium on Virginia Key, mixing dirt trail and pavement on a 4.167-mile yard every hour, with the field limited to 500 runners.
Edition note: Registration is open on RunSignup at $249 until December 14, 2026, or until the 500-runner limit fills; refunds are not allowed. Parking, packet pickup, basecamp footprints, crew access, aid and the final measured course map are still being finalized and will be published in the Athlete Guide before race weekend. Big's race page lists the race without a ticket category, and the organizer's FAQ says: "A calendar listing does not by itself establish a championship qualification or ticket status." Yardlore lists no earlier edition.
Peoria, Arizona, USA
A New Year fixed-time festival on a 1.42-mile dirt and paved loop at Peoria Sports Complex, with a 6-day race, rolling-start 72- to 6-hour races and 100- and 200-mile options.
Edition note: Registration is open on UltraSignup at late-tier prices, for example $795 for the 6-day, $470 for 72 hours, $325 for 48 hours and $250 for 24 hours, before tax and fees. Online registration closes Sunday, December 20 at 11:59 PM PT; Aravaipa also offers a mail-in entry form, a payment plan and race-day registration at the venue. No field caps are published. On October 20 the 2026–27 live results button on the organizer page had no link yet. UltraSignup’s race-day text names “Saturday, December 27” (2:00–6:00 PM) and 7:00 AM to noon each morning, while the organizer page lists check-in on Sunday, December 27 and race-day registration from 7:00 to 10:00 AM; December 27, 2026 is a Sunday.
Rice Lake, Wisconsin, USA
A 160-mile out-and-back winter race from Rice Lake on Wisconsin's Tuscobia State Trail, by foot, bike or ski, with water-only checkpoints, mandatory camping gear and a 65-hour limit on foot.
Edition note: The 17th edition runs December 31, 2026 to January 3, 2027, with the 160-mile run and ski starting Friday, January 1. It is the first under new organizers Kari Gibbons and Erik Raivo, announced on June 8, 2026, after Chris and Helen Scotch stepped away. Applications for this invitational event were taken on UltraSignup in August 2026 and are closed; fees are charged only on acceptance. The organizer's post gives the window as August 15–29, while UltraSignup says applications closed on August 21. If places open up later, late fees apply. On October 20 the course and schedule pages still listed the Winter Huskies checkpoint location as TBD, and the rules page kept an older line calling bivy sacks and sleeping bags optional, which conflicts with this year's mandatory sleeping bag, pad and bivy.
Águas da Prata, São Paulo, to Paraisópolis, Minas Gerais, Brazil
A 240 km (150-mile) non-stop race on the Caminho da Fé pilgrim route through the Serra da Mantiqueira, from Águas da Prata to Paraisópolis, with optional earlier finishes and a 68-hour limit.
Edition note: Entry is closed. Regular registration ended on July 31, 2026, the extension for Badwater and Brazil 135 veterans on August 31, and the 2027 roster was announced on September 7. The old domain brazil135.com.br showed a hosting error on October 20; the official site is brazil135.net. Sources differ on the time limit (68 hours in the organizer’s 2027 regulations, 72 hours in DUV) and on the international entry fee (US$1,540 on the rules page, US$1,560 in the regulations PDF, US$1,300 in DUV).
Bonneville County Fairgrounds and Sandy Downs Park, Idaho Falls, Idaho, USA
A winter backyard ultra in Idaho Falls, Idaho, looping 4.167 miles every hour through Sandy Downs Park from an indoor transition hall at the Bonneville County Fairgrounds.
Edition note: The fifth edition, and the first in January: the four earlier races were held in December from 2022 to 2025. Registration is open on RunSignup until January 6, 2027, with 76 of 110 places left on October 20. The 2025 race sold out. Big's race page lists the category as "Bronze", and the organizer's text there says Dizzy Horse "is a Bronze Qualifier that feeds into the Banana Slug Silver Qualifier". The organizer's site adds that the winner "on odd years" gets a paid, guaranteed entry into a Silver Qualifier. The organizer gives about 50 ft of climb per lap; Big's listing says 80 ft.
Island Park, Idaho, USA
A 200 km winter race on groomed snowmobile trails around Island Park, Idaho, by fat bike, ski or foot, on an unmarked course navigated by GPS, with three heated checkpoints and a water-boil test.
Edition note: The 2027 200K is listed for January 8–10, 2027, and the 30K and 60K for Saturday, January 9. Registration is open on Athlete360: the 200K costs $375, or $325 with the early-bird discount through November 27, 2026. On October 20 the 200K roster showed 17 entrants, three of them on foot and two on skis. The organizer's race-details page still showed the 2026 schedule, prices and refund dates, so 2027 race-week times and cutoffs had not been confirmed.
Erfoud, Morocco
A non-stop, food-self-sufficient Sahara race from Erfoud on parts of the MDS Legendary route, over 100 miles or 100 km, with a 40-hour limit and a 4 km/h minimum speed.
Edition note: Second edition. Registration was open on October 20, 2026 at €1,950 per person, with €100 off for the first 100 registrants. Cancelling between October 5 and November 8, 2026 forfeits 50% of the fee and there are no refunds after that; free postponement ends October 25, and a €250 postponement fee applies until November 29. The 2027 regulations page asked for a login when checked, so the rules here come from the organizer’s event and format pages.
Hill Country State Natural Area, Bandera, Texas, USA
A 100 km trail race of two counterclockwise 50 km loops on rocky, sotol-lined hills in Hill Country State Natural Area, with about 6,600 ft of climbing and a 25-hour limit.
Edition note: Registration is open on RunSignup. On October 20, 2026 the prices were $245 for the 100K, $160 for the Sunday 50K, $139 for the 25K and $160 for the Saturday non-competitive 50K, which had 22 places left. Entries after December 1 get other swag instead of a shirt. Tejas Trails gives no refunds, and deferral credit shrinks closer to race day. Bandera is a Western States qualifier for 100K finishers within 18 hours, but it is not a 2027 Golden Ticket race, and a 2027 USATF championship designation has not been verified here.
Bidiyah, Ash Sharqiyah, Oman
A five-stage, 165 km self-sufficient race across Oman's red, golden, and white dunes, with runners carrying their food and sleeping equipment.
Da Lat, Lam Dong, Vietnam
The 101.5 km 100K Langbiang runs from Lam Vien Square in Da Lat over Langbiang, Elephant Mountain and Pinhatt to the Clay Tunnel near Tuyen Lam Lake, with 5,570 m of climbing and a 29-hour limit.
Edition note: 100K entries are open until 11:59 PM (GMT+7) on December 25, 2026, or until full; the 50K and 20K are closed. The homepage and UTMB calendar give the event as January 7–10, 2027, while the entry page and UTMB’s announcement say January 8–10; every race starts on Saturday, January 9. The race header and details table checked on October 23 now agree on 101.5 km and 5,570 m of climbing, replacing the earlier conflicting figures. The 100K GPX was last updated on October 19, 2026. UTMB Live had no 2027 page on October 20.
Edale to Kirk Yetholm, United Kingdom
A non-stop January race along the full 268-mile Pennine Way from Edale to Kirk Yetholm, with about 10,700 m of climbing, five checkpoints and a 156-hour limit.
Edition note: Entries for 2027 opened at noon UK time on February 4, 2026, through a virtual queue, with a waitlist once places are filled. On October 20, 2026, the race page said “Check back soon for entry details” and the public 2027 roster showed no names, so current availability could not be verified from those public pages. The entry fee is £1,345. The 2027 time limit is 156 hours; the 2025 race pack gave 168 hours. The 2027 live tracking link had not been posted.
Torre, Serra da Estrela, to Nazaré, Portugal
A 306.8 km self-navigated non-stop race across Portugal from Torre, the highest point of Serra da Estrela, to Nazaré on the Atlantic, with eight support bases and a 74-hour limit.
Edition note: Registration is open on STOP and GO until the places sell out or December 31, 2026. On October 20 the current price was €630 (lot 3) and the entry list showed 71 names. The Portuguese event page now gives 306.8 km and +8,214 m, matching its support-base table. The English page still gives 303.8 km and +10,815 m; other older figures also remain in circulation. Check-in hours and the awards time also differ between the Portuguese and English pages, and the Portuguese regulations prevail. The organizer had not published a live tracking link on October 20.
Estrella Mountain Regional Park, Goodyear, Arizona, USA
A 101.3-mile desert loop race at Estrella Mountain Regional Park, combining two shorter red loops and three longer blue loops with a 32-hour cutoff.
Edition note: The 2027 event page was current at review but still linked the 2026 runner guide.
Voritsi village square, Heraklion, Crete, Greece
A backyard ultra based in Voritsi, Crete, with alternating daytime and nighttime routes and hourly starts until the last runner completes a final solo yard.
Edition note: Registration is open for January 16, 2027. The event banner spans January 16–17, but the rules give no fixed finish. Use the 10:00 AM start in the dated 2027 instructions; the older route page still says 11:00 AM.
Honolulu, Oʻahu, Hawaii, USA
Five 20-mile laps of rooty, muddy rainforest single-track in the mountains above Honolulu, with about 24,500 ft of climbing, 20 stream crossings and a 36-hour limit.
Edition note: Entry is closed. The 2027 lottery was drawn on August 8, 2026, and the selected runners and three category waitlists are posted on hurt100.com. Waitlisted runners can still be invited until December 31, 2026. Every entrant and waitlisted runner must submit eight hours of verified trail work by November 17, 2026. Runners who withdraw by November 17 get 50% back only if a waitlisted runner takes the place; after that there are no refunds, and entries cannot be transferred or deferred. The 2027 tracking and live-timing links had not been posted on October 20, 2026.

Israel's national 24-hour championship on a fast paved loop in Hayarkon Park, with qualifying standards for the headline race.
Coverack to Perranporth Airfield, Cornwall, United Kingdom

Edition note: The organizer lists registration open for 2027. The published course closure is Sunday, January 24 at 2:30 AM; follow your assigned wave and the official checkpoint limits. No race-day registration or waiting list is offered.

A 100 km mountain-trail race through Hong Kong's beaches, country parks, steep ridgelines, and extensive trail network.
Queen Elizabeth Park, Mackays Crossing, Kāpiti Coast, New Zealand
A backyard ultra in Queen Elizabeth Park on the Kāpiti Coast, north of Wellington, on a 6.71 km loop of paddock, coastal trail and ex-farm track over Wellington Anniversary Weekend.
Edition note: The third edition starts at 9:00 AM on Saturday, January 23, 2027. Entry opened on July 1, 2026, through eventplus and is limited to 150. Adult entry is $150; under-18 entry is $90 by email request. Until midnight on December 31, 2026, a withdrawn entry can be credited or transferred; until midnight on January 15, 2027, transfer only, both with an admin fee. The organizer says a live leaderboard link will be announced. Big’s race page labels the race “Bronze”.
Usery Mountain Regional Park, Mesa, Arizona, USA
A January backyard ultra at Usery Mountain Regional Park in Mesa, Arizona, with a 4.1667-mile trail loop by day and a road out-and-back from 8:00 PM.
Edition note: The fourth edition. Registration is open on UltraSignup and closes at 11:59 PM MT on Friday, January 8, 2027. Big's race page lists the category as "Bronze" and gives Phoenix as the location; the race is held at Usery Mountain Regional Park in Mesa. The ruck loop is 2.3 miles on UltraSignup, while Big's page gives 2.25 and 2.5 miles.
International Falls to Tower, Minnesota, USA
A 135-mile winter race on the Arrowhead State Trail from International Falls to Tower, Minnesota, on foot, bike or skis, with mandatory survival gear, three checkpoints and a 60-hour limit.
Edition note: The 23rd Arrowhead runs January 25–27, 2027. Applications opened on UltraSignup at 8:00 AM Central on September 1, 2026, and on October 20 UltraSignup showed registration closed since October 10, 2026; the entrant list is hidden. The organizer's rules page is headed 'for 2027' but still gives the previous year's gear-check and start dates (Saturday January 24, Sunday January 25, Monday January 26), so confirm the 2027 race-week times in the racer information. UltraSignup lists the start as 7:00 AM Monday, January 25, 2027. The 2027 Trackleaders tracking page had not been posted on October 20.

A high-level backyard ultra at Meadowood Special Recreation Management Area, built for deep performances in a small, highly supported field.

Patagonia to Superior, Arizona, USA
A 300.5-mile journey from Patagonia to Superior through Arizona’s Sonoran Desert and mountain terrain, with 19 aid stations and a 150-hour limit.
Edition note: The organizer and registration page agree on March 29–April 4, 2027. Their elevation totals differ, so no single climbing figure is asserted here; use the final runner manual and course files when released.

A 200-mile point-to-point on Western Australia's Bibbulmun Track, crossing tall forests, coastal scrub, dunes, beaches, and ocean cliffs.

A mountain 100-miler from Easton, Washington. For 2027 the organizer expects an alternate out-and-back route because of damage from the 2026 Three Queens Fire.

A single 100.2-mile loop from Pickett CCC Memorial State Park through the Big South Fork into Kentucky and back, run counterclockwise in 2026, with about 14,500 ft of climbing and a 34-hour limit.
Edition note: The advertised runner-registration deadline was October 21, 2026 at 11:59 PM CDT and has passed. The separately listed pacer deadline is October 24 at 5:00 PM CDT; it is not a late entry option for runners. The 2026 runner’s manual, last updated September 29, uses a 100.2-mile counterclockwise course; the homepage still lists 102 miles. Piney Butte became a no-crew aid station (drop bags still allowed) on September 29, and the September 19 training run was cancelled.
