Listed edition: Oct 18, 2025 – Oct 23, 2025
Format: Backyard Ultra
Distance: No single distance recorded — choose or confirm a target
Local start time: 7:00 AM Central Time on Saturday. The 2025 race started on October 18; the 2027 edition is listed for October 16.
Duration / cutoff: Each yard must be finished in under an hour, and every runner must be in the corral when the next bell rings, with no late starts. There is no set finish. The winner is the last runner to complete a yard, and if nobody completes one more yard than everyone else, there is no winner.
Crew and pacers: Backyard rules allow no personal aid during a yard and no one on the course with an active runner, including eliminated runners. Runners may leave the course only for restroom breaks. Crews help between yards.
Drop bags: Check the current race rules
