Oner

About this event

The ONER is a serious coastal ultra that traces 85 miles of the Jurassic Coast from Portland through to Studland. With around 100 runners taking on the challenge, this 24-hour race weaves through some of southern England's most dramatic terrain — clifftop paths, sandy stretches, and rocky coastal trails along a UNESCO World Heritage Site. It's known as one of the toughest coastal races in the UK, demanding both physical grit and mental resolve. The scenery is spectacular, but this is no sightseeing run: expect long hours on your feet, technical sections, and relentless coastal elevation. For experienced ultra runners seeking a proper test in a stunning setting.
