On March 26, 2026, Mathéo Jacquemoud got off his bike on the Promenade des Anglais in Nice, France. With the Alps behind him and the Mediterranean Sea ahead of him, his ski and bicycle journey was finally over after nineteen days.

What Was the Challenge?
Jacquemoud’s project, which he named L’Intégrale des Alpes, was straightforward in concept and almost incomprehensible in execution. The goal: traverse the entire Alpine arc, from Vienna to Nice, using only skis and a bike. Not a segment. Not a highlight reel of the best bits. The whole thing.
That meant 2,200 kilometers across 19 mountain ranges in four countries—Austria, Italy, Switzerland, and France. It meant summiting some of the most iconic peaks in the Alps, including Mont Blanc. The total elevation gain came to 86,000 meters, roughly the equivalent of climbing Mount Everest nearly ten times over.
Before setting out, Jacquemoud estimated the journey might take 30 days, but he did it in only nineteen.
The Numbers Behind the Feat
On skis alone, Jacquemoud covered 715 kilometers and 60,000 meters of elevation gain over 142 hours of moving time.
On his bike, he added another 1,474 kilometers and 25,840 meters of climbing across 61 hours.
In total, he was physically active for 200 hours over the 19-day span, completing 38 ski-to-bike transitions and averaging just 6 hours and 10 minutes of sleep per night.
What Made It So Hard
The weather was relentless from the start, and nowhere more brutal than in the Ticino Alps, where over 1.5 meters of fresh snow fell at 1,500 meters altitude. During the Swiss section, Jacquemoud and fellow athlete Clément Parisse attempted the Adler Pass multiple times before a storm finally forced them back to Saas-Fee. Rather than wait, Jacquemoud simply rerouted by bike to Zermatt and kept the traverse moving. There was no pause button.
Jecquemoud didn’t set out to break a speed record. The mountain conditions set the pace, and he had to make calculated decisions at every step. And yet, stepping off the bike in Nice, Jacquemoud said he wasn’t broken. Just a good tired, he offered. He felt he could have kept going for several more days.
Why This Matters to Mountain Climbers Like Sonam Saxena
The numbers of this story alone are impressive. But for mountaineers like Sonam Saxena, who has stood on the summit of Mount Everest and understands firsthand what the mountains ask of a person, Jacquemoud’s traverse speaks to something deeper.
Jacquemoud framed this project as a journey. His aim was to draw the most beautiful line possible through the Alpine arc, at his own rhythm, on his own terms. The clock was almost beside the point.
That philosophy will resonate with Saxena, who has reflected on how reaching Everest’s summit reinforced his belief that achieving so-called “impossible” goals is always within reach—not because the difficulty disappears, but because the right mindset reframes difficulty. Jacquemoud spent 19 days proving that exact point across one of the world’s great mountain ranges.
