The Aquathlon du Corbier is a swim-run race held in Le Corbier, situated at 1,550 metres in the Savoie mountains. It offers short S and XS formats, open to solo participants and relay teams. The swim takes place indoors in a heated 25-metre pool maintained at 29 °C, a distinctive feature for an aquathlon. Competitors begin in warm water before transitioning to a run in a winter mountain environment.
Savoie Maurienne Triathlon organizes this event, which is well-suited for triathletes seeking early-season practice without the commitment of a long race. The two-lane pool is also accessible to regular swimmers, offering activities like free swimming, aquagym, aquabike rentals, lessons, and a stopwatch for training. For the athletes, a key benefit is the transition practice: moving from a pool swim to a run at altitude, where the cold air and mountain conditions provide a distinct challenge compared to a typical city aquathlon.
