Conquer The Chilterns routes

Swim Course

The Swim takes place in the River Thames and navigates the world famous Henley Royal Regatta and Temple Island Meadows, the Thames has very little flow downstream in this area. The start will be in the River above Henley Management College.

The swim will start upstream, keeping the large swim buoys to your left. Please only take your wetsuit, goggles, hat and timing chip to the start area.

Bike Course

The Bike is a 3 lap course with one large climb per lap. Anytime lost going up will certainly be made going back down the Stonor Valley, which stretches for nearly 5 miles directly into Henley.

The Route takes you through the historical Hambleden Valley and down the Stonor Valley on the way home.

Run Course

The Run course will be an undulating climb overlooking breath taking views and landscapes in the final section of the event.
