Summit Backyard Ultra (Last Person Standing)

Summit Backyard Ultra is a trail backyard ultra in Marble Falls, Texas, starting from 2200 Manzano Mile. Runners have one hour to complete a 4.17-mile loop, then line up again at the top of the next hour and keep repeating that pattern until only one person remains. The race is run Last Person Standing style, where the winner is the final runner who completes a lap after all others have stopped or failed to finish within the hour. It was previously hosted by Pursue Your Summit LLC and now runs under Perspective Pacing, with a shirt deadline in late October and registration closing in mid-November.
