Easter 50 Ultra Challenge 2025

About the event

A challenge event you can take on at your own pace. The Easter 50 Ultra Challenge invites you to walk, jog or run a distance of your choice, along a signed route, with free food and drink at regular rest stops, plus support including medics, marshals and massage.

Get the ‘Ultra Challenge’ support and hospitality all the way – helping you to push yourself further and achieve something really special, while raising vital funds towards the next type 1 diabetes breakthrough.

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, taking in the wonderful countryside views.

With 50km, 25km and 10km challenge options available, there’s an Easter 50 Ultra Challenge for everyone – plus you can join as an individual or as a team of friends or family.

As you cross the finish line, you’ll get a hero’s welcome, a glass of fizz, an Ultra Challenge T-shirt, and a special medal to celebrate your achievement.
