Trophée d'Armor Winter Race 2026 — Saint-André-des-Eaux

In the quiet hours of early March, the Bétineuc leisure base in Saint-André-des-Eaux sheds its winter stillness as the members of Dinan Natation Sauvetage begin their annual ritual. For the local community, this gathering is the definitive start of the swimming season, drawing a dedicated group of regulars who return each year to test their endurance in the fresh, crisp waters of the lake. The Trophée d'Armor Winter Race 2026, scheduled for March 8th, maintains a focused, almost meditative atmosphere, emphasizing individual challenge over podium glory. Swimmers can choose from distances ranging from 50 to 1000 meters, with triathlon-style wetsuits permitted to manage the early spring temperatures. The event remains a core part of the local calendar, serving as a distinct alternative for those who prefer the calm of inland waters before heading to the coast for the Open Swim Stars La Baule later in the summer.

The landscape of the Guérande Peninsula

The swim itself offers a unique vantage point over a landscape steeped in Neolithic and medieval history. As you navigate the water, you are effectively tracing the perimeter of an area that has been a focal point of human settlement for millennia. To the west, the subtle rise of the land towards the Guérande plateau anchors the horizon, where the massive, 1434-meter long medieval walls stand as a testament to centuries of military engineering. This fortification was designed to protect the wealth generated by the nearby Pays Blanc salt marshes, which have supplied fleur de sel for generations. The aquatic environment here is a sharp departure from those coastal flats; you are swimming in proximity to the 'Pays Noir', a vast peat bog that provides a dark, earthy aesthetic to the surrounding Brière marshlands.

History is never far from the shoreline here. The nearby dolmen of Sandun, an 'allée couverte' overlooking the Brière, silently watches over the marshlands just as the Kerbourg dolmens—ancient tombs looted during the Roman era—remind visitors of the site's deeper, more turbulent past. While the region is famously punctuated by the Menhir of Bissin, known in local folklore as the 'Caillou de Gargantua', the swim remains focused on the rhythmic, clean lines of the lake. Participants receive a full race kit, including a commemorative t-shirt and a timing chip bracelet, ensuring that every effort—from the shortest 50-meter sprint to the 1000-meter endurance test—is accurately recorded as part of the regional circuit.
