Castle To Coast Triathlon
The Castle To Coast Triathlon is a point-to-point sportive triathlon from Dorney Lake near Windsor to Brighton Sea Front. The event combines a lake swim, a long road cycle through the Surrey Hills and a trail run across the South Downs to the seafront. It is organised by Active Training World and described as a non-competitive, sportive event that is not governed by British Triathlon competition rules. The event offers individual and team entry options; the team option requires two or three team members and a car to manage transfers between stages.
