Easter 50 Ultra Challenge 2025

From Windsor the ‘figure of 8’ route follows The Thames Path with fantastic views of the riverside & surrounding countryside, passing Eton College, and old Windsor before a snacks & drink stop at Runnymede. You follow ‘The Great Walk’ towards Windsor Castle with epic views as you get close. A lunch stop back at basecamp, before the 2nd 25 km loop – with more of the Thames Path, a final rest stop at Dorney Court, then back to the Racecourse where a loud cheer & celebration await.
