Road Bikes - Col de Joux Plane
Description
In cycling circles, the Joux-Plane pass is reputed as being one of the six most challenging passes in the French mountains, along with the Galibier, Izoard, Alpe d'Huez, Mont Ventoux and Tourmalet ascents.
This pass has often been a judge of peace for the riders of the Tour de France© and the Dauphiné Libéré©. Its ascent by bike from Samoëns, apart from the sporting performance which requires good training, is an opportunity to ride over a marvellous balcony overlooking the valley, then towards the Mont-Blanc massif in its most majestic profile... The road is closed to heavy goods vehicles and is not a major traffic artery, much to the delight of cycle tourists.
A few technical details:
The route presented here starts from Samoëns and follows the D354 road.
Departure altitude: 696 m
Arrival altitude at pass: 1684 m
Elevation gain: 990 m for a distance of 13.1 km, with an average gradient of 7.4%, but with passages of over 10%.
Difficulty: very difficult.
