UltraSwim 33.3 Switzerland

Lac Léman, or Lake Geneva, offers one of the world's most celebrated freshwater swims. Spanning 33.3 kilometers, this legendary stretch of water has captivated writers, artists, and adventurers for centuries, framed by the majestic Alps in the background. The swim takes place in late July when the lake reaches its warmest temperatures, up to a comfortable 26°C.
The Lake Edition unfolds over four days with six swims, starting from the historic Château de Chillon, passing through UNESCO-listed vineyards along the shore, and finishing in charming Swiss villages. The highlight is the signature crossing between Evian-les-Bains (France) and Lausanne (Switzerland), a symbolic swim across national borders.
Each stroke takes you past iconic landmarks like Freddie Mercury’s statue at Montreux Jazz Festival grounds, immersing you in both natural beauty and cultural heritage. By participating, you contribute to Léman Hope, the local charity supported by this event, ensuring your effort leaves a positive impact on the community.
Join us for an unforgettable journey through one of Europe's most picturesque settings, where every swim is more than just a race—it’s a celebration of nature and culture.
