Cornwall's Backyard Ultra

Cornwall’s Backyard Ultra is a unique endurance running event held in St. Eval, Cornwall. Participants run a 4.167-mile (6.7 km) loop starting on the hour every hour, repeating laps until only one runner remains.

The course loops around the old St. Eval airfield on open roads, with safety measures including high-visibility clothing and lights for night running. The event takes place in a private farming field that serves as race headquarters, with camping available for participants and supporters.

Emphasizing community and personal challenge, the race encourages runners of all levels to push their limits in a supportive atmosphere where persistence is celebrated over speed. Visit the organization's website for the most recent information.
