Challenge yourself on the North Downs 50 Ultra Challenge and champion Dogs for Good as you take on this rewarding and unforgettable event. Together, we can bring even more people and dogs together to make life possible.
Take on the North Downs 50 Ultra Challenge on Saturday 31 July 2027.
With lots of distance options available, you can walk, jog or run at your own pace – and fundraise for Dogs for Good.
Starting and finishing in Guildford, head along the North Downs Way towards an amazing view at St Martha's Church. The looped 50km route takes challengers through some lovely villages and the scenic Blackheath Common.
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!

- 50% off your registration fee
