This event is for experienced triathletes and is a great place for climbers. Forget the extension cord, it’s useless! After a warm-up of about 10 km, the gradients become very serious and make the thighs warm up until the station of Plaine-Joux. Beware then of the very technical descent, no performance is worth an injury. After a few kilometers on the flat, you will reach the lac de Passy, before moving on to running on shaded paths.

The bike course is on open roads, so please keep to the right and respect the traffic regulations. Overtaking is only possible from the left.

The Olympic race is open to relay teams. Two or three team members, three sports, one race!
