Castle to Coast

Dorney Lake, Windsor

Organiser's Description

An epic one day triathlon sportive from Windsor to Brighton. Start with a 2k swim at Eton Dorney, then a 65 mile bike ride down to Hassocks, and then it's on two feet for a half marathon trail run down to the sea front. This relaxed sportive style event is something new in the triathlon world, and a great way to spend a day out. Select from either finishing in Brighton or return transport to Windsor.


2 km swim, 65 mile bike, 13.1 mile run
