The Jurassic Coast Ultra Challenge is a multi-distance trek and trail event on the Jurassic Coast in Dorset. The route starts at Corfe Castle and proceeds via Swanage, Lulworth Cove and Durdle Door, reaching Weymouth at the approximate halfway point. The full 100 km route continues past Portland Bill and Chesil Beach to finish in Bridport via West Bay.

  • ~50 km
  • ~25 km

Support on the route includes covered marquee rest stops approximately every 12.5 km with larger facilities about every 25 km. Catering is provided at rest stops with snacks and drinks at the shorter intervals and meals at the larger stops, including options for different dietary requirements and lighter options for runners. The event uses a fully signed route with extensive pink arrows, GPS mapping in an event app, and a timing system that logs progress at rest stops. Medical provision includes on-site medics, podiatrists, massage teams, and a mobile emergency medical team linked to a 24 hour control room.

Logistics include camping packages, shuttle buses and transfers, parking at many finish locations, and a solo start option plus alternative formats such as an Ultra March option and a Trailblazerz option. Finishers receive a medal, finisher shirt, a glass of fizz and a finishers meal. Visit the organization's website for the most recent information.
