Conquer the Chilterns

Henley Showground, Hambleden Estate, Culden Faw, Fawley HENLEY-ON-THAMES. RG9 3AP

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.


Event merchandise is available for purchase during registration for delivery by the following weekend when ordered by Sunday.


All of our events are organised following government and governing body COVID-19 guidance. We will continue to ensure that we deliver safe and enjoyable events.


Entry on the day will be subject to availability and a £5 surcharge.
