Bonneville Backyard Ultra

Charleston, United States • 26 Apr 2025

The Bonneville Backyard Ultra is Utah's original last man standing ultramarathon, held at the Deer Creek Dam Trailhead in Provo, UT. Participants must complete a 4.167-mile loop every hour to remain in the race. The course features an out-and-back design, with approximately 2.08 miles in each direction.

The event emphasizes personal endurance and pushing one's limits, rather than just competition. Runners must be present at the starting corral when the bell rings to continue; failure to do so results in elimination.
