Autumn Harvest Backyard Ultra

The Autumn Harvest Backyard Ultra is a last-runner-standing race held at Pleasant Ridge Camp & Retreat Center in Marietta, South Carolina. All participants begin together at 8:00 a.m. on Saturday. There are no categories and no late starts. The format is straightforward: runners complete a 4.1-mile loop each hour, on the hour. Anyone who does not make the cutoff or return to the start corral on time is eliminated. The race continues until only one participant remains. The winner must complete a final full lap after at least one other runner begins that lap with them. Crews may provide assistance only between loops, not on the course itself, making the short breaks at camp crucial for eating, resting, and preparing. Each runner is allocated a 10x10 aid station space, with camping permitted within this area for the runner and their support crew. When runners finish a loop, they retrieve their race mug from the runner board, return their timing chip, and receive a milestone patch.
