Endless Day Backyard Ultra

Endless Day Backyard Ultra

Endless Day Backyard Ultra takes place in Richfield, UT, with the start/finish in Nielson Family Park at 555 N 600 E. The event uses a single 6.55 mile loop that begins every 90 minutes. Runners may continue to start new laps for up to 24 hours and must complete each lap within the 90 minute window. Participants who stop earlier still earn the distance they have completed.

Distances offered include:

• 10K
• Half Marathon
• Marathon
• 50K
• 50 Miles
• ~100 Miles

The course follows mostly flat dirt roads and farm fields, with only three city blocks of pavement between the park and the farm roads. The route offers views of the Pahvant Range and Red Hills. Aid is available at a full station in the start/finish park area and another station about halfway through the loop. Two self-serve coolers will be available given potential heat. Nielson Family Park is an entire city block, providing room for personal tents and base camps; areas near the Northern Pavilion will be roped off.

Registration is tiered by intended number of laps. There are regular and increased rates after the stated deadline. The race awards finisher milestone mementos and a race hat. The overall winner is the runner who goes furthest within the time limits; if several complete the last lap, whoever finishes that lap first is the winner.
