Mathilde Cartier
Professional Triathlete
Hyperactive since childhood, Mathilde Cartier has been a triathlete for the past eight years. After a turbulent adolescence spent far from any structured sports practice, she rediscovered the thrill of endorphins through running during her studies. Shortly after lacing up her trainers again, she discovered cycling—initially as a recreational pursuit. Before long, her competitive spirit resurfaced. Despite being a complete novice in swimming, she decided to challenge herself by entering her first triathlon. Her ranking was anecdotal, but the seed had been planted: she would commit fully. In just a few years, she progressed rapidly and began stacking podium finishes. She qualified for and competed multiple times at the Ironman 70.3 World Championships, as well as the Ironman World Championship in Nice. A trajectory that proves she was, quite literally, built for this. Naturally competitive, Mathilde considers it essential to measure herself against the best athletes in the world. This drive led her to pursue a professional license, which she obtained in 2025. She competes across Italy, France, Sweden and Austria, taking part in the Ironman Pro Series and ranking as the 15th Swiss woman in the PTO Rankings. She is excited to count on PHN's support for the 2026 season. And when the stopwatch stops, her sense of adventure takes over: ski touring, gravel riding, mountain biking, trail running, paddleboarding or kayaking. For Mathilde, Built For This means exactly that—having a body forged by triathlon, capable of carrying her through (almost) any outdoor adventure. What matters most is always pushing beyond one's limits.
Enzo Guebey
Professional Ice Hockey Player
Born in a small village at the foot of Mont-Blanc, Enzo grew up outdoors, between exploration, tinkering, mountain biking and mopeds. It was around the age of five that he fell in love with the sport he still practices today at the highest level: ice hockey. Hardworking, passionate and determined, the young man from Saint-Gervais left his cocoon early to join Switzerland and the Genève-Servette Hockey Club, where he joined the sports-studies program and managed to balance academic success with athletic performance. With GSHC, he won the Swiss U17 and U20 championships, before signing his first professional contract with his youth club. After three seasons in Geneva, Enzo continued his career in Zurich, then Davos, competing at the highest level of Swiss hockey. At the same time, he represents France on the international stage, being selected for national youth teams (U18 and U20), then for the French A team at the World Championships and the Olympic Games.
Stéphane Charlin
Professional Ice Hockey Goaltender
Swiss goaltender Stéphane Charlin has built his career on composure, discipline, and unwavering consistency. From his early development to competing at the highest level of Swiss hockey, he has distinguished himself through reliability, precision, and the ability to rise in decisive moments. As a modern goaltender, Stéphane combines athletic explosiveness with technical mastery and mental resilience. His game is defined not only by reflexes and positioning, but by his calm presence under pressure — a quality that separates good players from elite performers. Selected to represent Switzerland at national level, he embodies a new generation of goaltenders: intelligent in their preparation, relentless in their work ethic, and fully committed to continuous progression. For Stéphane, performance is never accidental. It is built through daily discipline, structured training, recovery, and a constant pursuit of marginal gains. Behind every save lies preparation. Behind every performance lies consistency. His approach aligns naturally with PHN's philosophy: no shortcuts, no compromises — just precision, reliability, and long-term performance.
Céline Von Potobsky
Hybrid Athlete — HYROX & Triathlon
Former professional football player turned hybrid athlete, Céline embodies evolution through discipline. After competing at the highest level in football, she chose a new challenge — stepping into the demanding world of triathlon and HYROX. A transition that requires more than talent. It requires structure, resilience, and the willingness to start again. Today, she is qualified for the HYROX World Championships and holds the Swiss National Record in HYROX Mixed Doubles (55'35). But performance is only part of the story. Disciplined. Determined. Relentless in her pursuit of progress. Céline moves forward the same way she trains — consistently, intentionally, without shortcuts. Her journey reflects what PHN stands for: Daily work. Hybrid performance. Long-term vision. From elite football to endurance and strength-based competition, she represents a mindset built on effort and precision.
