About the race
Babbitt’s Backyard Ultra is a backyard-style ultramarathon held on land belonging to Babbitt Ranches near Flagstaff, Arizona. Competitors run the same loop repeatedly; each lap is 6706 meters (4.167 miles) and must be completed in less than one hour. When a lap is finished, the remaining time within that hour is typically used to rest before the next lap. The event continues until a single runner completes the final lap and is declared Last Man Standing.
The loop runs through volcanic terrain with multiple eroding cinder cones, including the feature known locally as SP crater. The course surface is a mix of dirt trail and dirt road and includes about 150 feet of climb per lap. The event is scheduled for September 26, 2026, in Flagstaff, Arizona, and fields up to 100 participants. The current record for number of completed loops stands at 55. This race is classified as a Bronze bracket event; the winner receives a place in the Silver bracket Tartarus Backyard. The ranch setting may include cattle on or near the course.
