Two Tunnels Races

Bath, United Kingdom • 7 Jun 2026

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

Ticket information on the event page indicates tickets are currently sold out and that ticket sales close 1st June 2026. The organiser contributes £1 per runner to Sustrans to support maintenance of the Two Tunnels. Fundraisers taking part for Sustrans receive a free running vest and other items. Brickfields Park includes a children's playground and is noted as a place for spectators and participants to gather after the races. Visit the organization's website for the most recent information.
