Half Marathon Events

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! Cutting right under the city of the Bath, the two tunnels offer a truly unique running experience. The Somerset & 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 2 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. We are very happy to be supporting the ongoing work of Sustrans in maintaining the Two Tunnels by contributing £1 per runner to their charity. Looking to fund raise as part of your run, why not raise money for Sustrans? You will get a lovely free running vest and other goodies. Find our more here. In 2019 we donated £5,254 to Sustrans
