Endless Day Backyard Ultra
The Endless Day Backyard Ultra in Richfield, Utah is a timed loop event that was rescheduled from June 27 to October 17 because of unhealthy air quality from local forest fires. The format uses a repeated 6.55-mile loop that begins every 90 minutes; participants must complete each lap within that 90-minute window. The event runs for up to 24 hours and runners may stop at any time and still earn the distance they completed.
Milestone distances awarded by laps:
- 1 lap = 10K (90 minutes)
- 2 laps = Half Marathon (3 hours)
- 4 laps = Marathon (6 hours)
- 5 laps = 50K (7.5 hours)
- 8 laps = 50 Miles (12 hours)
- 15 laps ≈ 100 Miles
The course follows flat dirt roads through farm fields with views of the Pahvant Range and Red Hills. Only three city blocks of pavement connect Nielson Family Park to the farm roads. Aid support includes a full aid station at the start/finish park area called The Oasis, one aid station about halfway on the loop, and two self-serve coolers for extra cooling. Nielson Family Park offers room for personal tents and base camps; some areas near the northern pavilion will be roped off.
Registration fees are tiered by intended laps: 1–6 laps and 7–15 laps with higher rates after October 4. October weather in central Utah can be sunny, windy, snowy, or a combination, so participants should plan gear and hydration accordingly.
