How far can you go? Introducing the Endless Day Backyard Ultra
This isn’t your typical ultra.
👉 Every 90 minutes, you start a new flat dirt-road 6.55-mile loop
👉 Keep going as long as you can… up to 24 hours
👉 Stop when you want—and STILL earn your distance
🏁 Finishers earn real race milestones:
• 1 lap = 10K
• 2 laps = Half Marathon
• 4 laps = Marathon
• 5 laps = 50K
• 8 laps = 50 Miles
• 10 laps = 100K
• 15 laps = ~100 Miles
No pressure to be “last one standing”, well unless you are standing on the final lap.
Just you… the road… and one very long day.
🌾 Flat dirt roads. Farm fields. Big skies, in Richfield, Utah.
🐾 A course you’ll know by heart by the end.
