It features several short-format races: an individual XS triathlon, an S-distance team race for groups of 3 to 5, and an S-distance relay.
The program includes races for young athletes and adults, with separate events for ages 6-9 and 10-13. Previous editions also had youth categories, and the organizer maintains past results and photos online. Chatte is located near Saint-Marcellin, with the nearest train station approximately 1.5 km away. The race is accessible from Grenoble, Valence, and Saint-Martin-d'Heres.
