Windsor 50 Ultra Challenge

Looking for an active way to spend your Easter? Whether you're ready to conquer a 50 km Ultra, step up to a historic 25 km, or go all-out on a sharp and scenic 10 km, this challenge has something for everyone.

Starting from Windsor Racecourse basecamp, join over 2,000 adventurers on stunning looped routes that take you through Windsor Great Park with spectacular views of Windsor Castle, along the iconic Thames Path, past the historic meadows of Runnymede, and deep into the beautiful surrounding countryside.

With full support every step of the way, regular rest stops, and a buzzing celebration finish line back at basecamp, this is more than just a challenge – it’s an unforgettable Easter experience.

Lace up, get outdoors, and make your mark this spring!
