The Oner Ultra Trail Run

The ONER

The ONER is a single-stage coastal ultra along the Jurassic Coast held on 6th and 7th June 2026. The route is described as circa 85 miles, roughly 140 km, to be completed within 24 hours. Entry for the ONER is listed at £210.

The event is organized by Epic Endurance Events Ltd with support from Votwo Events and typically fields about 100 participants. The course runs from just outside Charmouth eastwards and finishes at the National Trust Shell Bay Car Park in Studland. The route includes the full circumnavigation of Portland and crosses coastal footpaths, beaches and tracks, including exposed cliff sections and parts that take place in darkness. If access to the planned route is restricted an alternative or an out and back route may be used.
