Windsor 50 Ultra Challenge

Take in the sights of Windsor Castle and the surrounding countryside in this Easter challenge!

Get active after the Easter holidays and take on a historic 50 km Ultra, a testing 25 km, or a sharp 10 km challenge at your pace as a walk, jog, or run – and fundraise for Winston’s Wish!

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, along the Thames Path, and taking in some 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, take on an Ultra Challenge – the UK’s No.1 Series of treks & trail challenges.
