The race

Les Défis des Chalets is a multi-distance trail event held in Saint-Maurice in the Chablais, offering four timed courses that range from 7.8 km and 430 m of gain up to 42.2 km and 3327 m of gain. The long course runs beyond marathon distance and carries a vertical that makes it a genuinely demanding day out. A 23.6 km and a 12.8 km option round out the programme for runners looking for something in between.
