A coastal ultramarathon circumnavigating the Isle of Anglesey along the official coastal path. Covering approximately 130 miles (209 km), the route links headlands, beaches, cliff paths and rural sections, with continual undulation typical of coastal terrain. Elevation is gained through repeated short climbs rather than sustained ascents. The race format, checkpoints, navigation method and time limits are specified by the organiser and should be consulted for full details.
