2023 Big Dog’s Backyard Ultra Results: Harvey Lewis Wins After 108 Hours, 450 Miles of Running – iRunFar

The format sees racers run a 4.166667-mile loop, called a “yard” in backyard ultrarunning, within a one-hour time limit, after which all finishers within the allotted time are tied for first place, and must present on the start line on the hour to go again. This continues until there is only one runner left standing, who must complete a solo yard to be awarded the win.

Just incredible.
