Cycle the Col de Joux Plane

Climb details:

From Samoëns (south side):

This ascent spans approximately 11.7km with an average gradient of 8.5%, peaking at sections as steep as 10%. The route is characterised by a series of challenging hairpin bends; 17 in total and steep sections, offering little to no respite throughout the climb. 

The initial half is somewhat less demanding, featuring stretches at 8-10%. However, after the sixth kilometre, the gradient intensifies, frequently approaching 10%, with certain segments reaching up to 13%. The latter part of the climb winds through forested areas, providing some shade, but as you near the summit, the landscape opens up, offering expansive views of the surrounding valleys and peaks.

From Morzine (north side): 

This route covers about 10.9km with an average gradient of 6.5%, though some sections ramp up to 11%. The initial 8 km present the most significant challenge, with gradients ranging between 9% and 11%. After passing the Col de Ranfolly at 1,658metres, there's a brief descent followed by a final 2km climb at a gentler 3.5% gradient leading to the summit. Along the way, cyclists traverse a mix of mountain pastures, hamlets, and small forests, encountering ski lifts and enjoying varied scenery.

Tour de France Legacy:

The Col de Joux Plane has been featured in the Tour de France 13 times since its debut in 1978. Notably, during the 2000 Tour, Lance Armstrong faced significant challenges on this climb, underscoring its difficulty. The pass has earned a reputation as a decisive segment in the race, often influencing overall standings.

Cycling tips:

• Preparation: Given the steep gradients and minimal recovery sections, it's essential to pace yourself from the outset. Ensure your bike is equipped with appropriate gearing to handle the sustained inclines.
• Weather considerations: The climb is exposed to the sun, especially on clear days, which can intensify the effort required. Starting early in the morning can help you avoid the peak heat. Conversely, weather conditions can change rapidly in mountainous regions, so be prepared for varying conditions.
• Descent caution: The descent, particularly towards Morzine, can be technical with sharp bends and variable road surfaces. It's advisable to descend cautiously, especially if unfamiliar with the route.

Conquering the Col de Joux Plane is no small feat, but the sense of achievement and the breath taking vistas of the Mont Blanc massif from the summit make the effort well worthwhile.
