The EDF Aqua Challenge Quiberon 7.5 km is an open-water swimming race in Quiberon, on the Morbihan coast of Brittany. It starts at 10:00 on a Sunday morning in late July; its distance classifies it as a serious swim, not a short beach event.
The race is part of both the Coupe de France and the regional cup, attracting licensed swimmers alongside those entering with a one-off open-water license. Participants must be at least 14 years old, and the cap limit is set at 150 swim caps.
