Wye Valley Tunnel Run 2025

Wye Valley Greenway and the Tidenham Tunnel

The Wye Valley Greenway will open for the time in its history on the 1st April 2021 and we are extremely excited to be bringing the first organised event to the Greenway and the Tidenham Tunnel. The charitable organisation Greenways and Cycleroutes has been behind reinvigorating this section of the Wye Valley Railway with a new lease of life; removing the old track, refurbishing and lighting the 1.1km long Tidenham Tunnel and resufacing a large portion of the route with a mix of compact stone path and tarmac. The Wye Valley Greenway is a shared use path, to be used and enjoyed by cyclists, walkers and runners.

The original railway ran from Chepstow to Monmouth. The last passenger train ran in 1959, but trains from nearby quarries only finally stopped in 1990.

The race starts at Wyedean School and heads along the rail path towards Tintern. Tidenham tunnel is 3km into the race and is itself over 1km long. There are great views along the wye valley as the two routes head to their turn around points before retracing their steps back to the finish line at the station.

If you would like to visit the tunnel and wye valley greenway please take a look at the visitors information page on the Wye Valley Greenway website which includes info on opening times and access points.
