Les Défis des Chalets - Trail d'Agaune

Les Défis des Chalets, also known as the Trail d'Agaune, is a trail-running event held in Saint-Maurice, Valais, in the French-speaking region of Switzerland. Taking place in October, it offers participants a variety of distances, ranging from an 8 km race to a marathon-distance mountain trail. The most challenging listed race covers 42 km with 3,400 meters of elevation gain, presenting a demanding mountain course rather than a flat road marathon. The event features the Défi 40k, Défi 25k, Défi 13k, Défi 8k, an 8k La Falaise Gourmande, and children's races of 1.5 km and 3 km. The 25 km option involves significant climbing, with 1,590 meters of gain over its distance. The 13 km and 8 km races maintain approachable distances while still incorporating elevation gain. This selection caters to experienced mountain runners seeking a strenuous challenge, local participants desiring a shorter trail race, and families with children looking for their own competitive opportunity.
