What you’re in for

A flat coastal route around the Chidham peninsula and along the shore paths of Chichester Harbour, with long views over the water to Bosham Hoe, Itchenor and East Head, and the Downs behind. If the tide is low, part of the course crosses the foreshore itself, which is unusual for a race. Climbing is minimal, 65m on the half. Two distances, 21.3k and 16.1k, start at 9:15 and 9:30 from One Church in Southbourne, with a 1pm cut-off. Canicross runners start five minutes behind each wave. The organiser asks runners to allow time for parking, including off-site, as starts go promptly.
