Get active after the Easter holidays and take on a historic 50km Ultra, a testing 25km, or a sharp10 km challenge at your pace as a walk, jog, or run! From a Windsor Racecourse basecamp, 2,000 adventurers will head out on looped routes through the Great Park with fantastic views of the Castle, on to Runnymede and along the Thames Path, all while taking in the wonderful surrounding countryside.

Join as an individual or as a team; you’ll get full support all the way, plenty of food and drink, a special medal, T-shirt and celebration finish back at basecamp and a great sense of achievement! Push yourself further in 2026 and take on an Ultra Challenge, the UK’s No.1 Series of treks and trail challenges.
