From the organizer

A truly special race that not only takes in many of Bath's beautiful attractions but also has the longest underground sections of any running race in the UK!

Cutting right under the city of Bath, the two tunnels offer a truly unique running experience. The Somerset & Dorset Railway closed in 1966 and until April 2013 the tunnels have been sealed and inaccessible. Thanks to the hard work and dedication of the Two Tunnels Group and Sustrans over 7 years, the two tunnels now have a new lease of life as a shared use path. The first tunnel; The Devonshire Tunnel is 408m long and the second Combe Down Tunnel is 1672m long. Both tunnels are well lit and well surfaced, and have recently been converted into a shared use path for the enjoyments of runners, walkers and cyclists looking to make the most of the city whilst remaining a flatter ground.

With a marathon, 3 different half marathons, 2 different 10kms, 5kms and 500m races there are events for all the family, and if they are not taking part, bring your friends and family to cheer you on; our start and finish will be in Brickfields Park in the middle of the city. A green park complete with children's playground and table tennis table, a great spot to sit and enjoy a picnic after the race.

  • Did the 10k in 2019

    Well organised - to make different race distances run so smoothly together must take some serious effort! The Tunnels didn’t feel crowded, the aid station was plentiful, and the finish line everything you could ask for - medals, chocolate, fruit... Have run this event 4 years in a row, will definitely be back!
  • Did the Half Marathon in 2018

    My first half marathon. It was never going to be easy due to the hot weather, I believe it peaked at 34 degrees during this race. Thankfully the 2 tunnels were a lifesaver, one being about 400m long and the other was about a mile long, these were dark and damp, this was amazing during the basking hot weather. Doing the half you end up going through these 4 times (running the half marathon required 2 laps of the course.) Even though there wasn't a lot of spectators, the support from marshals was great, and was a nice but different having to run alongside runners completing different distances (5k & 10K)
