Tunnel Vision Dawn Run 2026

The Tunnel Vision Dawn Run takes participants through the Oxendon Tunnel, a 422-metre passage on the Brampton Valley Way near Market Harborough, Leicestershire. This 5-mile trail race follows a flat, hard-packed out-and-back course. It begins at 6:30am for a dawn start, with an alternative evening option for those preferring the tunnel in darkness. Head torches are mandatory for the tunnel section. The dawn race offers sunrise views on the trail after emerging from the dark passage. Marshals and first aid are present, and the course is fully marked. Its straightforward design suits both experienced runners and those seeking a short race with a unique element. Mary Pearson organizes the event, providing medals for all finishers, prizes for top runners, and refreshments post-race.
