Big Tex Backyard Ultra

Stephen F. Austin State Park, San Felipe, Texas, USA · Trail

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.

Summit Backyard Ultra

Marble Falls, Texas, USA · Mixed

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.
