The challenge

Walk, jog, or run through a spectacular World Heritage coastline while fundraising for Alzheimer's Society!

 A start in Corfe Castle, the route heads down to Swanage, and along through Lulworth Cove, past Durdle Door, with ups and downs to Weymouth halfway. For full 100 km challengers, it’s past Portland Bill, Chesil Beach and on to West Bay before a finish line in the vibrant town of Bridport. 

There's half, Weymouth Marathon, quarter, and 10km challenge options too. Join up to 3,000 adventures as an individual or as a team - you’ll get full support all the way, plenty of food and drink, optional camping and transfers, a special medal, t-shirt, celebration finish and a great sense of achievement! 

You could even push yourself further in 2026, taking on an Ultra Challenge – the UK’s number one series of treks and trail challenges.
