7k Run Bath: Scenic Adventure to Tucking Mill Viaduct

Route Overview & Local Insights

Experience one of the most unique running paths in the City of Bath with this 6.6km out-and-back trail. Characterized by its incredibly flat profile—featuring just 22 meters of ascent—this route is a dream for runners seeking a consistent tempo or a gentle recovery session. You’ll be running on a 100% paved surface along the historic Two Tunnels Greenway. The highlights of the journey are the converted railway tunnels, including the Combe Down Tunnel, which provides a cool, sheltered environment and even features a "musical" light installation. It is an immersive, traffic-free experience that culminates with the breathtaking sweep of the Tucking Mill Viaduct before you head back.

This route follows the footprint of the old Somerset and Dorset Joint Railway, a line that once linked Bath to the south coast before closing in the 1960s. As you cross the Tucking Mill Viaduct, take a moment to look out over the Midford Valley; this area was once the home of William Smith, the "Father of English Geology," who lived at Tucking Mill while surveying the local strata. Locally, the Greenway is a prized community asset, seamlessly blending Bath’s industrial heritage with the lush greenery of the surrounding Somerset countryside. Just remember if you are planning a late-night session that the tunnel lights are switched off between 11pm and 5am!
