Two Tunnels Marathon
Two Tunnels Marathon is a marathon held in Bath, United Kingdom, in August.
The event is built around two disused railway tunnels, the Devonshire Tunnel at 408 metres and the Combe Down Tunnel at 1,672 metres. Both are lit and have a good surface underfoot. The programme at Brickfields Park also includes a fun run, 5km, 10km, half marathon, 50km and relay formats alongside the marathon.
Route choice depends on the ticket. The flatter routes are almost entirely tarmac, with a short stretch of grass at the start and finish. Hillier options mix tarmac with woodland trail and stone paths, while the city routes use canal towpath and river path. The marathon distance is not officially measured, whereas the shorter distances and the 50km carry UK Athletics measurement.
