9k Run Bath: Scenic Journey Along the Two Tunnels Path

Route Overview & Local Insights

Experience one of the most unique running adventures in the UK on this 9.4km out-and-back route through the heart of Somerset's rolling landscape. Starting near Twerton, this fully paved course follows the historic reimagined Somerset and Dorset Joint Railway line. The highlight is undoubtedly the passage through the Combe Down Tunnel—the longest cycling and running tunnel in the country—where you’ll be accompanied by a subtle orchestral soundtrack and cool, crisp air. With a gentle gradient and a manageable 71m of total ascent, it is an ideal choice for runners looking for a consistent tempo session or a scenic recovery run away from Bath's busy city traffic.

Steeped in industrial heritage, the Two Tunnels Greenway connects the Georgian elegance of Bath with the lush beauty of Midford Valley. Running this path feels like a journey through time; as you exit the Victorian-era engineering of the Devonshire and Combe Down tunnels, you are greeted by the stunning sight of the Tucking Mill Reservoir, once the home of the "Father of English Geology," William Smith. Local runners recommend checking your watch as the tunnels are unlit between 11pm and 5am, and while the path is sheltered, the tunnels maintain a constant cool temperature year-round—a perfect escape during the summer months.
