Ambassadors of La Rosière
La Rosière is proud to support five passionate athletes who embody the true spirit of the mountains: pushing limits, freedom and authenticity. Whether they are trail runners, cyclists, skiers or adventurers, they all share one thing in common – a strong bond with our resort. Meet our ambassadors!
Arthur Joyeux-Bouillon – The tireless ultra-trailer
Born in Grenoble in 1994, Arthur grew up with the mountains. Skiing, climbing, mountain biking… until trail running, which he discovered in 2013 and quickly became his passion. Since then, he has shone on the world’s biggest races: 3rd at the TDS in 2021, 2nd at the Istria 100 in 2023, multiple UTMB top 10 finishes… and of course, four-time winner of the Trail de La Rosière (record 4h20).
In 2020, he made a mark with the “Mont Blanc Challenge”: a round trip from La Rosière to the summit of Europe’s roof in 20h05. For Arthur, La Rosière is the ultimate training ground: “The mountains are the greatest sports field. Here, I feel free.”
Damien Vuillier – The long-distance rider
A cycling enthusiast since his teenage years, Damien has recently embraced ultra-cycling, where he is already stacking victories: Race Across France, Race Across Belgium, 24h of Le Mans solo…
A long-time lover of La Rosière, he comes every year to enjoy the legendary passes and hidden roads of Tarentaise. For him, the resort is the perfect starting point to explore and push his limits. As an ambassador, he is proud to help highlight cycling in La Rosière.
Côme Girardot – Pure audacity
Originally from Bordeaux but raised in La Rosière, where he has skied and biked since childhood, Côme is a true all-rounder in extreme sports. His specialty: døds diving, a spectacular jump discipline where he already holds 4 world records, including a 44.3 m dive in 2024.
Always chasing adrenaline, he also shines in freeride and shares his adventures authentically on social media. Since 2025, he proudly represents La Rosière, a resort that for him embodies freedom and pushing limits.
Marie Goncalves – The next generation of trail running
At just 26, Marie combines top-level sport with her law studies. Initially a middle-distance runner, she switched to trail after the lockdown and quickly rose: French vice-champion of long trail in 2022, world team champion in 2023, and double winner of the 22 km Trail de La Rosière.
Attached to our resort where she first discovered mountain running, she now trains here every summer. Her motto? “Believe in what you do, do what you believe in.”
