Take on the Windsor 50 Ultra Challenge in support of Dogs for Good and enjoy a route packed with iconic scenery and sweeping parkland. Every kilometre you cover helps us bring more people and dogs together to make life possible.
Take on the Windsor 50 Ultra Challenge on Saturday 17 April 2027.
With lots of distance options available, you can walk, jog or run at your own pace – and fundraise for Dogs for Good!
From the Windsor Racecourse basecamp, 2,000 adventurers will head out on a looped route through Windsor Great Park with fantastic views of the castle, before going on to Runnymede and along the Thames Path – taking in some wonderful surrounding countryside.
Sign up as an individual or as a team and get full support all the way, with plenty of food and drink. All routes are fully marked, and there'll be massage and medical care available and marshals walking the route with you. Finish with a great sense of achievement and a celebration!
If you're fundraising for Dogs for Good as part of the challenge, sign up before 30 September 2026 to get:
- 50% off your registration fee
- A free Ultra Challenge t-shirt
- Full support along your training journey thanks to the Training Virtual Challenge and Ultra Challenge Community
