The 2 Mile Henley Swim is a challenging open water event set in the River Thames at Temple Island Meadows during the Henley Swim Festival. Swimmers can compete in either the Suits category, wearing wetsuits for added buoyancy and warmth, or the Skins category, following traditional open water swimming rules without a wetsuit. This scenic and rewarding swim is ideal for experienced swimmers looking to test their endurance in the iconic Henley course.

The water quality of the Thames at Henley is regularly monitored, and the river is known for its clean, flowing conditions. While the temperature can vary depending on recent weather, it typically ranges between 16-20°C in summer. Swimmers should be prepared for the natural feel of open water, including cooler temperatures compared to a pool.
Participants are not required to wear wetsuits, though they are recommended for younger or less experienced swimmers to provide warmth and buoyancy. A brightly colored swim cap is typically required for safety and visibility. The event is fully lifeguarded, ensuring all swimmers feel secure as they take on this short but exciting swim in the historic setting of Henley-on-Thames.
