Open Swim Harmonie Mutuelle la Baule

Legend suggests that the giant Gargantua once strode across the Guérande Peninsula, accidentally dropping a massive stone known as the 'Caillou de Gargantua' near the marshes. While this myth explains the origin of the standing stones scattered throughout the territory, today’s open water swimmers find themselves navigating the same coastal edges that defined the landscape long before such tales were told. As you line up on the sand in August, you are starting your swim on one of the longest stretches of coastline in Europe, a sweeping arc of the Côte d'Amour that extends toward the horizon. The energy of the water here carries the weight of centuries, from the ancient megaliths like the Pierre de Coicas that stand inland, to the legacy of Saint Liphardus, whose influence remains etched into the names of the surrounding communes.

Race day conditions

Participating in the Open Swim Stars La Baule 2026 means engaging with the Atlantic currents that have shaped the nearby Pays Blanc salt marshes for generations. These marshes, a distinctive white mosaic visible from the air, contrast sharply with the dark peat of the Brière region further inland. Swimmers can choose from distances ranging from 500m to 5000m, navigating a maritime environment governed by the rhythm of the tides. Those familiar with the region's colder, earlier season challenges, such as the Trophée d'Armor, will find that the August date offers a significantly different thermal profile. While you focus on your sighting and stroke, you are effectively swimming parallel to a coastline that has remained a constant navigation point since the Neolithic era, when structures like the Kerbourg dolmens were first established overlooking these same waters.
