We have a range of different events over the summer which have different names according to the route. The 'Return Ticket' events are out and back within the Two Tunnels. The 'Hilly Tickets' go out through the Two Tunnels and come back over the hills that the tunnels pass through. The 'City Tickets' go through the tunnels, along the Kennet & Avon canal and into the heart of Bath on a circuit tour of the city.

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. Why not use your run to raise money for the Sustrans? You'll get a  free lovely running vest and other goodies! Find out more here.

About - Two Tunnels Railway Races

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.

Events - Two Tunnels Challenge and Beast of Bath Challenge

Following on from our very popular Cheddar Gorge Challenge series we are offering two new Challenge events in Bath which challenge runners to take on their first half marathon or marathon running event. Our program of events build up Mini Challenge runners from 5km, 10km through to half marathon and our Challenge events build up from 10km, half marathon and marathon. All Mini Challenge and Challenge runners who take on and conquer the Challenge will be awarded a special commemorative trophy to mark their achievement.
The Two Tunnels Challenge events see runners making the most of the incredible Two Tunnels and the surrounding countryside. All the events, 5km, 10km and half marathon and marathon are on flat and fast courses and makes an ideal series of events for runners looking to take on their first half marathon or marathon.

With 3 events, incorporating the Two Tunnels race on 10th May,  located on different hills surrounding the city runners will enjoy the very best views of Bath on these tough off road running races. Whilst it is unlikely you will set a PB on any of these courses, you will enjoy a unique challenge and be crowned a Beat of Bath runner for taming all the hills of this beautiful city.
