Two Tunnels Races

Two Tunnels Races in Bath, UK, organized by Relish The Great Outdoors, offer a unique underground running experience alongside city scenery. The courses pass through the Devonshire Tunnel (408m) and the longer Combe Down Tunnel (1672m), both well-lit and surfaced as a shared-use path—the longest underground section for UK race distances. Start and finish are at Brickfields Park in Twerton.

Distances include 500m and 2km Colourburst; 5km (two waves); 10km options (Return and various waves); 10km Hilly; Half Marathon (Return and Hilly variants). The event caters to families and beginners, with a charity element supporting Sustrans (£1 per runner) and over £30,000 raised to date. Tickets are sold out.
