Experience Utah's original Backyard Ultra, a thrilling last man standing ultramarathon. Participants must complete a 4.167-mile loop each hour to stay in the race, featuring an out-and-back course with approximately 2.08 miles each way. Runners gather at the start line, where a painted corral signifies eligibility for each loop. A series of whistles countdown to the start, and the bell marks the top of the hour. Those not in the corral when the bell rings are eliminated. This challenging race emphasizes personal limits over competition, pushing runners to discover their true potential.
