Take on this spectacular World Heritage coastline as a walk, jog, or run all whilst fundraising for an important cause. Join over 3,000 Challengers heading out from basecamp by Corfe Castle on eight different distance options from 100km to 10km – there’s a Challenge for everyone.

The route heads down to Swanage, and along the coastline to Lulworth Cove, past Durdle Door, with some challenging hills before Weymouth at halfway. For full 100 km Challengers, you’ll head past Portland Bill and along Chesil Beach before a finish line in the vibrant town of Bridport. 

Join as an individual or as a team and get ready to experience full support every step of the way. Regular Rest Stops packed with food and drink, hot meals, fully marked routes, massage and medical care, marshals on course and walking the route with you, and of course an unbeatable community. There’s even camping and transfer options available so you can plan your whole weekend smoothly.

Join the UK’s #1 Series of treks and trail runs in 2027, and push yourself further with the Jurassic Coast Ultra Challenge.
