Royal Parks Half Marathon
Join Dementia UK and tackle the Royal Parks Half Marathon, run past London’s iconic and historical landmarks for families facing dementia.
Join 3,000 adventurers of all experience levels and ages and walk, jog or run the spectacular Jurassic Coast – a World Heritage Site. Choose from the Full 100km challenge, 3/4 Challenge (75km), a 50km half challenge, the Jurassic Marathon (42km), a 25km Quarter Challenge or a gentler 10km distance. There’s a challenge for everyone!
Starting from Corfe Castle, the route heads to Swanage, then along to Lulworth Cove and past Durdle Door, with ups and downs all the way to the Weymouth halfway point.
100km challengers will continue past Portland Bill and nature reserves, and along the western end of Chesil Beach to West Bay’s famous cliffs, before a finish line celebration in vibrant Bridport.
You’ll receive great hospitality all the way, including free food and drink at regular rest stops along a fully signed route, plus support from medics, marshals and massage therapists. As you cross the finish line, you’ll get a warm welcome from the cheer squad, a glass of fizz, a t-shirt and a special medal to celebrate your achievement.

Emma and AnnaThe walk was both emotionally and physically challenging. But I can’t explain how lovely the support was around. Locals left out chairs with rest stops, with glasses of water and oranges; not to mention the moral support from the other people taking part.
