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 and ending in a private farming field, with the course extending around the old St.

Eval airfield on open roads. The race begins on the hour every hour, with runners repeating the loop until only one remains, making it a test of grit and resilience with no set finish time. Camping is available on-site for participants and supporters, fostering a community atmosphere.

High visibility clothing and lighting are recommended for safety during night laps. The event encourages all levels of runners to push their limits in a supportive environment. Visit the organization's website for the most recent information.
