The Wye Valley Ultra Marathon (WYVUM 30) is a single-loop trail race based in Chepstow that follows the Wye Valley Walk to Monmouth and returns on the Offa's Dyke Path. The route runs through ancient woodland and riverside sections, passing points of interest such as Giant's Cave, the 365 Steps, Lovers Leap, Tintern Abbey, Cleddon Falls, Redbrook and the Kymin before returning to Chepstow.

The WYVUM HALF is a separate single-loop route of 14.5 miles that follows the Wye Valley Walk to Brockweir and returns on the Offa's Dyke Path. The full WYVUM route continues north to Monmouth while the half peels off and loops back to Chepstow.
