This event marks the 10th Year Anniversary of the original Royal Windsor Trail Run which first took place in 2013. Back, bigger & better than ever with a 10km, Half Marathon & Marathon to choose from now is your chance to race in the original Royal Windsor Trail Run on Sunday 21st May 2023.

The course will pass the historical sites of Windsor, Boveney Lock, Bray, Dorney, Maidenhead and Eton, finishing with Windsor Castle in front of you!

This event is not designed to be a gruelling cross country through deep mud and puddles, but aims to be a fun, friendly and fast trail run along one of England’s most historic courses - read about the course story here. We hope that our onsite facilities, commentary and music provide plenty to keep other halves and little ones entertained, ensuring a day out for all the family while you run.

If you have never visited the Thames Valley or Windsor & Eton, this could be the perfect opportunity.
