6k Run Forest of Dean: Scenic Trail to Tidenham Tunnel

Route Overview & Local Insights

This 6.1km out-and-back route offers a captivating blend of smooth surfaces and historical intrigue as you run from Sedbury toward the impressive Tidenham Tunnel. With a gentle ascent of 47m, the course is manageable for most fitness levels, yet it earns its "hilly" rating through steady undulations that keep your legs engaged. While nearly half the route is paved, you’ll experience a mix of terrain that transitions from the edge of the village into the heart of the Forest of Dean’s lush greenery, passing the turquoise waters of the National Diving and Activity Centre along the way. The turnaround point at the tunnel provides a natural milestone, making it an excellent choice for a focused tempo run or a scenic recovery jog.

Steeped in industrial heritage, this path follows sections of the old Wye Valley Railway, which once served as a vital artery for transporting timber and stone through Gloucestershire. The Tidenham Tunnel itself is one of the longest cycling and walking tunnels in the UK, recently restored as part of the Wye Valley Greenway to reconnect local communities with the stunning landscape of the Wye Valley Area of Outstanding Natural Beauty. Running here feels like stepping through time; the cool air near the tunnel entrance and the surrounding ancient woodland provide a refreshing microclimate even on warmer days. It is a must-run for those who appreciate how the UK’s railway history has been repurposed into world-class green infrastructure.
