CHALLENGE 100 KM

4 stages – 100km – 7100m d+

MONDAY 21 JULY 2025 Stage 1 The Pied Moutet tour

29km / 2000m d+

A first day to discover the Oisans! The route passes through the main hamlets of Les 2 Alpes (Mont-de-Lans, Bons, Venosc) but above all offers breathtaking views of the Oisans and its villages. This hilly route is ideal for a good warm-up. This hilly course is ideal for a good start. However, you will have to keep your feet under you for the final part of the stage: the ascent of the Alpe de Venosc and its 600m of positive difference in altitude in just over 2 km!

TUESDAY 22 JULY 2025 Stage 2 From Diable to La Fée ​

21km / 1300m d+

Direction the first beautiful altitudes for this second day! Right from the start, we attack with the Machiavellian climb to the Diable (2400m) before plunging into superb scenery with a more magical spirit. This stage full of contrasts should delight many!

THURSDAY 24 JULY 2025Stage 3 Lunar Jandri 3200

21km / 1300m d+ 

What an extraordinary experience! Starting and finishing at an altitude of 3200m, it’s going to be a crazy experience! The often lunar scenery is interspersed with exceptional panoramas and high altitude lakes.

FRIDAY 25 JULY 2025Stage 4The lakes of the Écrins

 29kms / 2500m d+

This is THE final touch, the explosion of beauty on this last day! The Ecrins National Park is a marvel, and rightly so: it’s highly protected. That’s why a number of measures apply on this day and why the number of participants is limited. For the privileged few, 2 extraordinary lakes are on the programme: the famous Lauvitel and the no less beautiful Lac de la Muzelle.

CHALLENGE 50 KM

4 stages – 50km – 3250m d+

MONDAY 21 JULY 2025Stage 1The Ridge of Pied Moutet

14km / 700m d+

A beautiful 1st day! 6 hilly kilometres to get into shape before discovering the beauty of the Crête du Fioc on this side of Pied Moutet. A stage with rolling parts, a beautiful climb, a spectacular descent: in short, the challenge of the Muzelle is launched!

TUESDAY 22 JULY 2025Stage 2The Diable

12km / 800m d+

The climb of the Diable is a “Must”, an ascent not to be missed in Les 2 Alpes. Because its profile is varied and interesting, but also because the views over the Vénéon Valley are grandiose!

THURSDAY 24 JULY 2025Stage 3Target Jandri 3200

10km / 700m d+ 

What an extraordinary experience! Starting and finishing at an altitude of 3200m, it’s going to be a crazy experience! The often lunar scenery is interspersed with exceptional panoramas and high altitude lakes.

FRIDAY 25 JULY 2025Stage 4The assault of Venosc

14kms / 1000m d+

The ascent of Venosc, a myth that absolutely had to be included in the race programme! Before climbing these 3 terrible kilometres, you’ll have a chance to get a feel for the terrain on the way down before branching off onto an ultra-technical path to reach the rare fairly flat section of the day. So, are you ready for the assault?
