The Wild Wye SwimRun on 5 July 2026 is a popular and unique 13km running race with a difference, set in the lower Wye Valley.

Starting next to the iconic Chepstow Castle, competitors will run northwards through Gloucestershire for around 6km, including passing through the 1086-metre Tidenham Tunnel on the former Wye Valley Railway. They then swim across the River Wye at high tide, a distance of about 100 metres, and then run back to Chepstow on the Welsh side.

The second ‘half’ of the run is slightly longer, totally off-road and rather more undulating than the first. The finish line is at Piercefield Park, adjacent to Chepstow Racecourse.

This event is organised by the Severn Area Rescue Association (SARA) who will provide safety cover for the river crossing. Competitors who do not wish to swim can pay extra and SARA will take them across by boat.
