Cross Triathlon de Cournon is a small off-road triathlon held in Cournon-d'Auvergne, near Clermont-Ferrand in France's Puy-de-Dôme. It takes place in late March and offers XS and S formats, suitable for first-timers and triathletes seeking a short, intense effort. The race is conducted as a time trial, with swimmers starting individually in the pool, one per lane every few minutes, rather than a mass start.
The swim is designed to be accessible; crawl is not mandatory, and organizers welcome participants who prefer breaststroke or are new to triathlons. Following the swim, the bike leg utilizes straightforward VTT or gravel trails along the Allier riverbanks, making an older mountain bike suitable. The run is flat, maintaining a welcoming feel without sacrificing engagement. PUISSANCE 3 COURNON organizes the event, and the combination of pool swimming, trail cycling, and flat running provides a unique challenge for experienced athletes while remaining open to beginners.
