Défi de la Salamandre 2026 (Coupe France Eau Libre) — Villiers-sur-Loir

The Défi de la Salamandre, held annually in July, offers a comprehensive range of distances from 200m up to a 25km marathon swim. Organized by USV Natation, this event takes place in the Plan d’eau de Villiers-sur-Loir, a 16-hectare reservoir established in 1990 following the development of the high-speed rail line. The water quality is recognized by the Pavillon Bleu d'Europe label, a status maintained consistently since 2010. Swimmers follow paths that cut through the Loir river valley, passing beneath the concrete Chantereine bridge, which has served as a modern crossing point since 1984.

Historical currents and landscape

As you navigate the course, the environment reflects a long history of local defiance. Villiers-sur-Loir served as a notable center of resistance during the 1851 coup d'état, and the area's independent spirit remained evident in the 1870 plebiscite, where voters defied the regime under the guidance of figures such as the local doctor Silly and the teacher Jean-Baptiste Michel Launay. While pushing through these waters, you may catch sight of the 12th-century Saint-Hilaire church, which holds 16th-century murals depicting the 'Dit des trois morts et des trois vifs' and a distinct Saint Christopher. Along the shoreline, the Saint-André hillside features caves carved directly into the rock; historically utilized as dwellings and wine cellars, these subterranean spaces maintain a stable temperature throughout the seasons, contrasting with the surface water conditions encountered during the race.

Local lore in the water

The landscape is steeped in the legend of the Serpent Hole, which recounts a dragon once terrorizing the region during the reign of Childebert I. According to the tale, a prisoner named Brayanus secured his liberation by constructing a chariot armed with long steel blades to dispatch the creature as it drank from the Loir. Today, the water remains a hub for the community, drawing both competitive swimmers and those focusing on club records. Participants should be prepared for the specific logistics of this river-fed venue, where the event schedule and start times are carefully coordinated by the organizers to ensure clear transit through the identified race loops.
