The 2018 date for the Henley Classic swim will be announced soon. 

A 2.1km (1.3 miles) up-river swim along the course of the Henley Royal Regatta, the swim traditionally starts at dawn with a torch-lit procession to the riverbank.  The event is held very early on the Sunday morning before the Wednesday start of Henley Royal Regatta.
