Henley Classic Swim The Henley Classic Swim is a 2.1km (1.3 miles) up-river swim along the course of the Henley Royal Regatta. The event is a unique opportunity to swim along one of the most beautiful and famous stretches of open water in the UK. The swim traditionally starts at dawn, with a ¼ mile torch-lit procession to the riverbank before the action begins. The event is held very early on the Sunday morning before the Wednesday start of the Henley Royal Regatta. Details of the 2019 Henley Classic Swim yet to be announced.
