HMV Cyclo Challenge - L'Iserane Climb

Climb to the top of the Col de l'Iseran, Europe's highest cycling pass!

Description

The Iserane is the route up the Col de l'Iseran by bike. Starting from Bonneval sur Arc, you pedal between walls of snow up to Europe's highest road pass. A legendary climb! For this event, the road is reserved for bicycles.

The Haute Maurienne Vanoise Cyclo Challenge consists of 6 climbs, each more unique than the last.

The ascent of the Col de l'Iseran, the highest road pass in the Alps at 2,770 m, is a must for all cyclists. With its 970 m elevation gain from Bonneval-sur-Arc, this climb remains etched in the memories of thousands of amateur and professional cyclists alike.

How does the HMV Cyclo Challenge work?
Add up the elevation gain of each climb to reach the different levels *.

Each participant can register on-site at the start of the climb and will receive an HMV Cyclo Challenge kit that allows them to track the elevation gain of each of the 6 climbs in the area: Iserane, Mont Cenis, Aussois, Orgère, Valfréjus, and Bellecombe.
Some climbs can be done several times if you feel up to it!

3 suggested objectives:

Bronze level: Achieve 1,000 m cumulative vertical drop
Silver level: Reach 2,000 m of cumulative vertical drop
Gold level: 3,000 m cumulative vertical drop

At each level, win goodies from our partners.

Then enter the draw to win the grand prize!
--> Bronze level: your name will appear 1 time,
--> Silver level: your name will appear 2 times,
--> Gold level: your name will appear 3 times!

Push yourself and try to accumulate the most vertical drop!

* Participation in the HMV Cyclo Challenge is not mandatory. You can take part in the cycle touring climb on closed roads without registering.

You’ll have the chance to ride back down the pass toward Val d’Isère. Our Tarentaise partners: the Val d'Isère Tourist Office and its Club des Sports are associated with this cycling climb, with a joint departure from their side of the Iseran. The climb on the Val d'Isère side will not count toward the HMV Cyclo Challenge!

Part of the climb takes place in the heart of the Vanoise National Park. Please respect the specific rules that apply (notably a ban on dogs, even on a leash, whose presence could disturb wildlife). Drones are also prohibited in the heart of the Vanoise National Park, also to preserve the tranquility of wild animals).

The D902 road will be closed to motorized vehicles for the occasion from 8:30 a.m. to 1:00 p.m.
