Cross Triathlon des Falaises d'Ault 2026

Cross Triathlon des Falaises d'Ault takes place in early June in Ault, a town on the Hauts-de-France coast near the Bay of Somme. This off-road triathlon is held at the base of the Ault cliffs, featuring a sea swim, mountain biking, and running, distinct from a closed-road city course. The commune of Ault and Club Olympique de la Bresle organize the event, which includes youth races alongside adult S and M formats. The swim occurs in the sea, the bike course crosses mountain-bike terrain between Onival and Bois de Cise, and the run extends through Ault into the Woignarue area. The event offers youth triathlon and duathlon options, catering to participants beyond experienced adult triathletes. Some event listings also refer to it as Triathletion Nature des Falaises d'Ault, reflecting its nature as a coastal triathlon centered on the cliffs, the town, and the rugged character of cross racing.
