Défi du Lac Bleu 2026 — Morillon

About the race

The Défi du Lac Bleu in Morillon is not just a swimming competition; it is a profound test of human resilience set against the breathtaking backdrop of the French Alps. Held in late March, this event invites swimmers to embrace the invigorating, icy embrace of the Lac de Morillon, where water temperatures typically hover between a bracing 6.5 and 7 degrees Celsius. For those who thrive on the challenge of cold-water swimming, this event offers an unparalleled connection to the raw, alpine wilderness of the Haute-Savoie region.

Organized by the CN Scouts Region Cluses, the Défi du Lac Bleu has established itself as a premier gathering for enthusiasts of open water swimming, drawing participants who are as much in love with the mountain air as they are with the discipline of the sport. The atmosphere is one of mutual respect and camaraderie; here, the 'cold' is a shared badge of honor. The event is intentionally inclusive, offering a wide spectrum of distances from a 50m sprint to a 1km 'Extrême' challenge, alongside team relay options, making it a fantastic venue for both competitive athletes and those looking to push their personal boundaries in a safe, controlled environment.

Morillon itself is a gem of the Giffre Valley, a place where traditional Savoyard architecture meets the dramatic peaks of the Alps. Whether you are coming to conquer the 1km distance or to join a relay team, the experience of emerging from the crystal-clear, glacial-fed lake with snow-capped mountains reflected on the surface is something that stays with you long after the adrenaline fades. After the race, you will find that the local hospitality is just as warm as the lake is cold.
