Swim 1,000m

A straight 1,000m swim up the tidal estuary at the beautiful Cuckmere Haven. The swim will head up the river but with a high tide there will be negligible current. The close proximity of the riverbank will make for a great spectator friendly swim.



Mountain Bike 22km

The bike route will follow the official “red route” in Friston Forest for two laps totalling approximately 22km. This is a challenging course with some tough climbs, but is not overly technical making it accessible to less experienced mountain bikers. Approximately 420m (1,380ft) elevation.
