Wye Valley Tunnel Run 2026

The Wye Valley Tunnel Run takes place in July at Wyedean School in Sedbury, Gloucestershire (postcode NP16 7AA). The event offers a half marathon, 10K, marathon, and Colourbust runs, catering to standard road-distance runners and those seeking a colour-run format. Most routes follow a disused railway line, providing a flat, firm surface. The courses are clearly marked and marshalled. Past results are accessible for participants wishing to compare their times. Fundraising is facilitated via GoFundMe.
