Take on a 50 km Ultra, a  historic 25 km, or a sharp 10K challenge – and get active. From our Windsor Racecourse basecamp we will head out on  looped routes through the Great Park with fantastic views of the Castle, on to Runnymede, along the Thames Path, and take in some wonderful surrounding countryside. It’s full support all the way, and a celebration finish back at basecamp.  great challenge to enjoy with family, friends, or as a solo adventure!
