Backyard Ultra - Summit Trail Racing

Registration

The Backyard Ultra hosted by Summit Trail Racing in Marble Falls, Texas, is a unique endurance event where participants run a 4.1667-mile loop every hour until only one runner remains. The course features a flat, wide 2.08-mile trail loop during the day, with a mix of trail and road sections at night to maintain variety. This officially sanctioned race, part of the 2026 United States Backyard Ultra National Team series, emphasizes strategy and endurance, requiring runners to return to the start within 60 minutes each loop.

The event offers primitive camping, crew access, and aid stations with water, Tailwind, and snacks, creating a supportive atmosphere for competitors. Visit the organization's website for the most recent information.

Always double-check with the organizer's website – things can change, and we might have sprinted past a few details!
