Smurf's Backyard Ultra

Results: 2026

Nobody completed one more yard than everyone else: Macpherson and Sinnott are both credited with 24 laps and neither started the 25th, so under the race rules there is no winner. The organizer’s results sheet lists backyard and Mini Backyard runners together.

Event Overview

A Cairns backyard ultra on the trails of Smithfield Mountain Bike Park, with hourly starts and a separate six-lap introductory event.

Course & Terrain

Repeated 6.7 km yards on dirt road and mountain-bike singletrack at Smithfield Mountain Bike Park.

Key course features to know before comparing this race:

• Rainforest and pine-forest singletrack on the Flat Snake, Echidna and Greenfields trails
• Three on-course water stations at about 2, 3.3 and 4.2 km
• Smurf dress-up lap (yard 3) and the Speedy Smurf lap (yard 6), with A$200 for the first man and woman across the line

The 2026 guide describes a 1.6 km out-and-back on open dirt road, a pass back through the event precinct, about 1.3 km more of dirt road, then mountain-bike singletrack: 1.3 km through rainforest and pine forest on Flat Snake, a clearing, and about 2 km on Echidna and Greenfields before a short dirt-road run to the corral. The organizer calls these the park’s easier trails; trail shoes are its first choice, especially when wet, though road shoes work. The trails stay open to mountain bikers, and runners must give way. Night laps on the singletrack are slower, and the course is marked with reflective tape and LED lights.

Heat and humidity are the main opponent. The organizer gives October averages of about 29°C (84°F) by day and 21°C (70°F) at night, with rain less likely than in the summer wet season. Its 2026 guide forecast highs in the high 20s and lows in the low to mid 20s, with some showers, and warned of a real risk of dehydration on the day laps. Much of the loop is under rainforest canopy, but the opening out-and-back on dirt road is unshaded. Nights are warm, though rain can make an extra layer welcome.

Why This Race Matters

Smurf’s Backyard Ultra is organized by Cairns race director Joshua “Smurf” Duff of Smurf Endurance Sports, and he bills it as Far North Queensland’s only official backyard ultra. Duff’s first backyard was the 2022 Old Mates Backyard Ultra at Upper Barron on the Tablelands, which Adam Fox won with 19 yards. The race moved to Smithfield Mountain Bike Park, on the James Cook University grounds, under the Smurf’s name in 2023, and 2026 was the fourth Smurf’s edition. Big’s Backyard Ultra lists it as a Bronze race. Unusually, it crowns both a last man and a last woman standing. The 34-yard record dates from 2023, when Fox and Rhys Williams stopped together and nobody won.

Historical benchmark notes in the directory record (verify current records with the linked official sources):

• Course record: Adam Fox and Rhys Williams, 34 yards, 2023 (they stopped together, so there was no winner)
• Women: Kelly Romano-Inverardi, 25 yards, 2025
• Outright winners: Adam Fox, 26 yards, 2024; Norman Eigl, 28 yards, 2025
• 2026: no winner after Murray Macpherson and Ben Sinnott both stopped at 24 yards; Kelly Romano was last woman standing with 23 yards

Preparing for a Race Like Smurf's Backyard Ultra

The backyard ultra race guide covers the format as a whole. These guides go deeper:

• Backyard ultras explained: Rules, distance math, current records and how a race ends.
• Backyard ultra training plan: A 16-week framework with hourly-loop rehearsals and a printable worksheet.
• Backyard ultra race strategy: Loop pacing, the routine between loops, sleep and knowing when to stop.
• Backyard ultra nutrition: A fueling framework to test for eating and drinking between loops.

Best Fit

• Backyard first-timers, who can try six laps in the Mini Backyard
• Runners who want to test themselves in tropical heat and humidity
• Women chasing a last-woman-standing title, since the race crowns one

Planning Notes

• Practice the exact hourly routine: loop, eat, foot check, bottle refill, and back to the start. The format rewards repeatability.
• Train for terrain-specific fatigue. Technical trails and mountain courses demand downhill durability, hiking efficiency, and reliable night lighting.
• The directory marks this as having comparatively simpler logistics. That editorial label is not a safety rating; verify cutoffs, terrain, support, crew access, and withdrawal procedures.
