Two Tunnels Races

Bath, United Kingdom • 17-7 Aug-Jun 2025

The Two Tunnels Races, held in Bath, UK, offer a unique running experience featuring the longest underground sections in the country. The course passes through the historic Devonshire Tunnel (408m) and Combe Down Tunnel (1672m), part of the former Somerset & Dorset Railway, now a shared-use path. Starting and finishing at Brickfields Park in central Bath, the event includes a variety of distances: 5km, 10km, half marathon, marathon, 50km solo and relay, plus fun Colourburst runs for families.

The routes are well-marked, mostly on tarmac with some trails, and supported by multiple feast stations offering water, snacks, and electrolyte drinks. The races support Sustrans charity and provide a friendly, inclusive atmosphere for runners of all levels. Visit the organization's website for the most recent information.
