Bath Two Tunnels Race August 2026

The Bath Two Tunnels Race in August takes runners beneath Bath, featuring the UK's longest underground section for each race distance. This August event, held at Brickfields Park in Bath, Somerset, offers distances from a 5K and Fun Run up to a 10K, half marathon, marathon, and ultra. The course runs directly under the city via two tunnels, giving the event a distinct character compared to typical road races around Bath. RunABC organizes the race. Past results from earlier editions are available, and runners interested in a charitable aspect can utilize GoFundMe fundraising in conjunction with their registration.
