Le défi de la Salamandre 10 km is an open-water swimming race at the Villiers-sur-Loir body of water in the Vendômois area of Loir-et-Cher, in France’s Val-de-Loire region. It is part of a French Open Water Swimming Cup stop, with a wider program that includes eight different events.
The race is still young, with its third edition on the Cup calendar, but it already draws a sizable field for this setting. Participation has jumped from 175 swimmers to nearly 400 expected, so the 10 km sits inside a busy weekend of racing rather than a small standalone swim.
