Backyard Ultra - Summit Trail Racing

The Backyard Ultra hosted by Summit Trail Racing in Marble Falls, Texas, is a unique "Last Person Standing" trail race featuring a 4.1667-mile loop that participants must complete every hour. Runners continue looping until only one remains, with no pacers allowed. The course includes a flat, wide 2.08-mile trail loop by day and a mix of trail and road at night to maintain variety.

The event offers primitive camping, RV access, and crew support at the start/finish area, providing water, Tailwind, and snacks. This officially sanctioned race is part of the 2026 US Backyard Ultra National Team selection and promises a challenging, community-driven atmosphere.
