Backyard Ultra - Summit Trail Racing
Marble Falls, United States • 21-26 Nov 2026
Event Overview
The Summit Backyard Ultra is a trail race held in Marble Falls, Texas, following the traditional backyard ultra format. Participants must complete a 4.17 mile loop every hour, on the hour. The event continues until only one runner remains on the course. To be crowned the winner, the final participant must successfully complete one last solo lap within the time limit.
Race Format
The competition is a "Last Person Standing" event. Each participant has exactly 60 minutes to finish the 4.17 mile course. If a runner finishes the loop in less than an hour, they may use the remaining time to rest before the next lap begins. Runners who fail to complete a loop within the hour or are not present at the start line when the next hour begins are eliminated from the race.
Participant Information
The event takes place at the Manzano Mile in Marble Falls. All participants receive race swag as part of their registration. There is a specific cutoff date in late October for runners to be guaranteed an event shirt. This race was previously organized by Pursue Your Summit and is now managed by Perspective Pacing.
