Bonneville Backyard Ultra
The Bonneville Backyard Ultra is a Backyard Ultra format ultramarathon held in Provo, UT, on an out-and-back course along Deer Creek Reservoir. The course measures one loop of 4.167 miles, with about 2.08 miles each way, and is described as mostly smooth and very runnable.
Runners must complete one loop every hour on the hour. A corral is used to track who is continuing each hour; if a runner is not inside the corral when the bell sounds on the hour, that runner is out. The event uses audible signals to mark the countdown: 3 whistles equals 3 minutes to go, 2 whistles equals 2 minutes, 1 whistle equals 1 minute, and the bell signals the start exactly on the hour. The rules prohibit late starts and pacers, and the race continues until a single runner remains.
The format emphasizes repeated hourly efforts, mental endurance, and potential sleep deprivation due to the restart cycle. Organizers note they may invite a small number of waitlisted runners to serve as standby participants on race day. Additional event details cover gear, rules, parking, and crew information. Registration availability and fees are provided by the organizers, and registration closes April 20. Visit the organization's website for the most recent information.
