Xtrem Triathlon

3.8 KM 

Exclusive in France, the AlpsMan Xtrem Triathlon starts with an intense adrenaline rush with a night boat departure. The participants will board the Libellule, a cruise boat, to reach the center of Lake Annecy between the bay of Talloires and the castle of Duingt. After a boat ride in a hushed atmosphere, the boat stops and the participants jump off one by one to reach the starting line. The top start of this day will be given at 5:30 am and the triathletes will dash in a blue and limpid water for 3,8 km of effort. They will leave on the beach of Saint-Jorioz to go to the bike transition zone on the esplanade of Saint-Jorioz.

Dismissal time: 7:30 a.m. - after this time, participants will not be allowed to ride their bikes on the course

180 KM 

The athletes will have to face a demanding course in the heart of the Bauges with a start and finish on the beach of Saint-Jorioz. A route promising beautiful passages at the top of the Semnoz and in the Bauges. You will have to cover 180 km and face more than 4000m of positive altitude difference to hope to start the running part. A real journey that will delight mountain bike specialists.

42 KM 

To finish the race in style, the run course offers an exceptional finish with 3 common loops to be completed up to "Le Tournant" Km24.6. At this precise point, only runners arriving before 5.30pm will be able to climb to the summit of the Semnoz to become TOP FINISHER. The other competitors will finish the marathon by completing 2 additional loops with passages along the lakeshore and the cycle path, finishing in the village of Saint Jorioz and thus becoming LAKE FINISHER.

A site known internationally for the beauty of its harmonious landscapes but also for its favorite playgrounds for sportsmen.

Lake Annecy will be the scene of a unique race start on board a boat! Participants will dive into the middle of the lake, classified as the purest in Europe, and then cycle through a real mountain stage, before admiring the panorama of the "blue lagoon" and its grandiose landscapes! Infinder, the marathon will take runners on a course tailor-made for a breathtaking finish at the top of Semnoz for the first and in the village of Saint-Jorioz.
