A 100 mile point-to-point ultramarathon following St Oswald’s Way from Holy Island (Lindisfarne) to Chollerford in Northumberland. The route traces historic coastal and inland paths, linking shoreline sections, farmland tracks, woodland trail and upland terrain as it travels south through the county. Elevation is moderate but continuous, with rolling climbs rather than sustained mountain ascents. The race structure, checkpoints and support arrangements are defined by the organiser’s official guidance and should be consulted for full logistical detail.
