Level Water are the official charity partner for the Henley Classic! This swim gives you the opportunity to swim the stunning, world-renowned 2.1km Henley Royal Regatta course at dawn. This is the ONLY time you will be able to have a safe supervised swim on the course, while it is completely closed to boat traffic.
“The event starts with a short walk to the official regatta start, where the first swimmers will enter the water, just as the sun is rising. This River Thames swimming experience takes you past all the famous Henley Regatta landmarks including the Barn Bar, Phyllis Court and the Members’ Grandstand. As the church and bridge come into sight in the early morning sun, you reach the end of your swim at the Official Regatta Finish.
After a short walk back to the event area you are welcomed by the smell of coffee and breakfast, into the hub of swimmers exhilarated by what they have accomplished before most of the country wakes up.”

The water temperature at the Classic depends upon both the outside temperature and the quantity of rainfall in the days and weeks running up to the event. It is therefore very difficult to predict.
Based on previous years, at the end of June, we would expect the water to be between 17 and 19 degrees centigrade.
