Wye Valley Tunnel Run

The Wye Valley Tunnel Run is a scenic running event held at Wyedean School in Sedbury, UK, featuring 10km, half marathon, and marathon distances. The courses primarily follow the flat, shaded Wye Valley Greenway, an old railway line, including a unique 1.1km stretch through the refurbished and lit Tidenham Tunnel. The 10km and half marathon are out-and-back routes with varying tunnel distances, while the marathon involves two laps with a 3-hour cutoff to start the second lap.

The event offers well-marked routes, multiple feast and drink stations, and colorful medals for finishers. It also includes a family-friendly Colourbust fun run on the school football pitch. Visit the organization's website for the most recent information.
