About the event

A challenge event you can take on at your own pace. The Jurassic Coast Ultra Challenge invites you to walk, jog or run a distance of your choice, along a signed route, with free food and drink at regular rest stops, plus support including medics, marshals and massage.

Get the ‘Ultra Challenge’ support and hospitality all the way – helping you to push yourself further and achieve something really special, while raising vital funds towards the next type 1 diabetes breakthrough.

Join 3,000 adventurers of all experience levels and ages taking on the spectacular Jurassic Coast – a World Heritage Site. Choose from the full 100km challenge, 75km, a 50km half challenge, a 25km quarter, or even a 10km distance. Starting from Corfe Castle, the route heads to Swanage, then along to Lulworth Cove, past Durdle Door, with ups and downs all the way to the Weymouth halfway point.

For 100km challengers – it’s past Portland Bill, nature reserves, along the western end of Chesil Beach to West Bay’s famous cliffs, before a finish line celebration in vibrant Bridport. It will test spirit and determination but is totally achievable with good preparation and the Ultra Challenge support.

As you cross the finish line, you’ll get a hero’s welcome, a glass of fizz, an Ultra Challenge T-shirt, and a special medal to celebrate your achievement.
