ARCHIVED RACE: Two Tunnels Half Marathon, 10km, 5km, Colourburst @ Brickfields Park, Bath, England, United Kingdom on 04 June 2022

A truly special race that not only takes in many of Bath’s beautiful attractions, but also has the longest underground section for each race distance in the UK!

Large custom medal and amazing post race fest stations.

The Half Marathon, 10km, 5km are all officially measured accurate routes.

Cutting right under the city of the Bath, the two tunnels offer a truly unique running experience. The Somerset and Dorset Railway closed in 1966 and until April 2013, the tunnels had been sealed and inaccessible. Thanks to the hard work and dedication of the Two Tunnels Group and Sustrans over a period of 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 tunnel, 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 enjoyment of runners, walkers and cyclists looking to make the most of the city whilst remaining on flatter ground.

With an ultra marathon, 50km relay, marathon, 3 different half marathons, 2 different 10kms, 5km, 2km and 500m Colourburst 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 is at Brickfields Park in the middle of the city which also has a children’s play ground and is a great spot to sit and enjoy a picnic after the race.

Time: 10:00 am – 1:30 pm
