Easter 50 Ultra Challenge 2025

The Easter 50 Challenge invites you to walk, jog or run a distance of your choice, along a sign-posted route, with free food and drink at regular rest stops, plus support including medics, marshals and massage.

From the Windsor Racecourse base camp, 1,500 adventurers will head out on looped routes through the Great Park with fantastic views of Windsor Castle, on to Runnymede, along the Thames Path, and takes in some wonderful countryside.

With 50km, 25km and 10km challenge options available - there's a challenge here for everyone – and you can join as an individual or as a team.

As you cross the finish line, you’ll get a big welcome from the cheer squad, a glass of fizz, t-shirt, and a special medal to celebrate your achievement.
