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 no set finish time; runners continue completing laps until only one remains, making it a test of grit and resilience. Camping is available on-site for those competing long-term, and safety measures include high-visibility clothing and lighting for night running.

The event fosters a supportive community atmosphere, encouraging all levels of runners to push their limits. Visit the organization's website for the most recent information.
