Walk, Jog, or Run a 50km Ultra or take on the 25km half challenge-and make next Easter weekend one to remember.
From our Windsor Racecourse base camp 1500 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 takes in some wonderful countryside. You’ll get full support all the way, a few post Easter surprises, a celebration finish at base camp, and a BBQ meal. It’s a great way to kick off the 2023 Ultra Challenge season, and to get in shape for summer.
Your entry includes free food and drink at regular rest stops, plus support including medics, marshals and massage. As you cross the finish line, you’ll get a glass of fizz, t-shirt, and a medal to commemorate your achievement
