Join us this year and Conquer the Chilterns in the heart of the Thames Valley, only an hour away from London.
This is one of the most scenic events in the country with a fantastic course around the Chiltern Valley and banks of the River Thames.
The swim takes place in the Thames and navigates the world-famous Henley Royal Regatta and Temple Island Meadows.
The cycle is a lapped course with one large climb per lap. Any time lost going up will certainly be made coming back down through the Stonor Valley, which stretches for nearly 5 miles directly into Henley.
The run route will include an undulating climb overlooking breath-taking views and landscapes in the final section of the event.
