Two Tunnels - June 2026
Two Tunnels is a multi-distance running event based in Bath with the start and finish at Brickfields Park. The course passes through two former railway tunnels that were reopened as a shared use path. The longer tunnel, Combe Down Tunnel, is 1672 m long and the shorter, Devonshire Tunnel, is 408 m long. Both tunnels are described as well lit and well surfaced.
The tunnels follow the route of the Somerset & Dorset Railway, which closed in 1966 and remained sealed until April 2013. Restoration and conversion into a shared path took seven years and involved the Two Tunnels Group and Sustrans.
Event distances include:
- Ultra marathon
- 50km relay
- Marathon
- Three different half marathons
- Two different 10km races
- 5km
- 2km
- 500m Colourburst
