ambassadors: LA ROSIÈRE, LAND OF adventures

Arthur joyeux-Bouillon

Arthur was born in Grenoble (Isère) in 1994. Mountain sports have always been part of his life, and he enjoys downhill skiing, ski touring, climbing and mountain biking.

It was in 2013 that he fell in love with trail running after taking part in his first race. He has now moved on to ultra-distance and has already proved that he has the talent to take on the best in the sport. He finished 3rd in the TDS in 2021, 9th in the MIUT in Madeira in 2019, 9th in the CCC Mont Blanc in 2018 and 2nd in the ISTRIA 100 in 2023. He finished 7th in 2022 and 9th in 2023 in the legendary UTMB race! Arthur is a member of Team On running.

You’re sure to see him at the Trail de La Rosière on the 40km course, where he has won the last 4 editions and has the reference time of 4h20!

In 2020, Arthur took part in the ‘Défi Mont Blanc’ with Fabien Antolinos, which consisted of a round trip to the summit of Mont Blanc from La Rosière, taking in an eye-popping route. In total, the route was 92km long and included 6000m of D +/-, with a large part of the ascent at altitude. For the first time, they achieved this performance in 20:05!

“I run in the mountains because I like the feeling it gives me. It’s the biggest sports ground you can find. I feel free and I can go wherever I want. There are no limits!”

DAMIEN vuillier

Damien has been involved in competitive cycling since the age of 15, having raced at the highest amateur level for many years. In recent years, he has also ventured into the world of ultra-cycling.

In a short amount of time, he has already built up an impressive track record, with standout victories such as the Race Across France (1100 km), the Race Across Belgium (1040 km), the Race Across Paris (1030 km), the 24 Hours of Le Mans solo (924 km), as well as the Last Man Riding events in Vaucluse and La Rosière.

For several years now, Damien has spent his holidays in La Rosière with family and friends. He fell in love with the resort, drawn to its family-friendly spirit and preserved authenticity. For him, it’s the perfect place to unwind, go hiking and enjoy a variety of activities—but above all, to indulge his passion for road cycling. La Rosière provides privileged access to many legendary mountain passes, as well as lesser-known but equally stunning climbs. He is truly honoured to have been chosen as an ambassador for the development of cycling in the resort.

Côme girardot

Originally from Bordeaux and a regular on the slopes of La Rosière since childhood, Côme Girardot has always had a deep connection with the mountains. Since birth, he has returned year after year to ski and mountain bike in the Espace San Bernardo. It was here that his passion for outdoor sports and his strong taste for adrenaline were born.

An extreme sports athlete, adventurer, and committed skier, Côme stands out in a discipline as spectacular as it is little-known: døds. In October 2024, he made history once again by setting his fourth world record with a breathtaking 44.3-metre dive, combining technique, boldness, and a steely mindset.

Always in search of new thrills, he constantly pushes his limits—whether flying off a cliff or freeriding through deep powder. Alongside his feats, he shares an authentic behind-the-scenes look at his life as an athlete through inspiring videos and projects on social media.

Since 2025, Côme has joined the La Rosière ambassador family—a resort that perfectly embodies his values: freedom, nature, and pushing boundaries. For him, skiing here brings back the emotions of his very first runs while passing on his passion to the next generation.

If you’re looking for him on the slopes, chances are you’ll find him at the snowpark or carving down the north face of Mont Valaisan!

Marie Goncalves

At the age of 26, Marie is a top-level sportswoman as well as a student lawyer, no less!

Marie grew up in a sporting family, with her mother a trail runner. Naturally, she started athletics at the age of 7. She gradually specialised in middle-distance and cross-country running, and didn’t really start trail running until a little after the quarantine lockdown.

A member of the Asics Elite Team, Marie has racked up a string of results in recent years: runner-up in the 2022 French long-distance race, world champion in the 2023 trail run team and 28th in the individual race. She also won the 2021 and 2023 editions of the 22km Trail de La Rosière.

Marie is particularly attached to La Rosière, as it was here that she did her first trail runs in the mountains. We’re delighted to be able to count her amongst our athlete ambassadors and to have her come and train in our beautiful mountains from the summer of 2024.

“Believe in what you do, do what you believe in.”

Sophie lechasseur-gavaggio

Sophie Lechasseur, a passionate skier from Saint-Rivière du Loup in Quebec, has always had a smile on her face and an eye for the mountains. She started club skiing at the age of 5. Skiing became an escape for her, a way of winning, pushing her limits and feeling the thrill of speed. Sophie quickly showed an exceptional talent for skiing, recording some impressive times: she reached the top 15 in the national FIS rankings.

Her story then took her to Whistler, British Columbia, the kingdom of freeride. In 2014, Sophie arrived in France for a three-week stay that turned into a new life. She discovered couloirs, mountaineering, and was amazed by the accessibility of mountains just a few hours away. In the summer of 2016, she set down her bags in the Tarentaise and got involved in teaching skiing. She can now see the French peaks from her window, ready to hit the slopes with every snowfall, while introducing her two children to the joys of skiing.

In winter 2022-2023, Sophie joined the team of La Rosière ambassadors. This new adventure has strengthened her bond with the resort, where she loves to come to recharge her batteries and share her passion for nature with her family. Whether she’s teaching her daughters to ski or enjoying freeride escapades in the powder, La Rosière offers Sophie a versatile experience, perfectly suited to a mother with a passion for snow sports.
