Baptiste Chassagne

Trail runners push their bodies to the ultimate level of physical and mental endurance. When others’ natural urge to stop kicks in, ultra trail runners are just getting started. They find their daringness at 10,000 meters elevation gain, on a narrow mountainside trail, 150km into a grueling course. Now, four of these elite trail runners are part of the TUDOR family.

MEET THE TUDOR TRAIL RUNNERS

Baptiste Chassagne is a rising French trail runner whose career is beginning to be marked by breakthrough performances on the international stage. His most defining result came with a standout performance at the Ultra-Trail du Mont-Blanc, where he surprised many by contending with the elite field and establishing himself among the sport’s emerging names. Not to mention his stellar performance finishing 2nd in the UTMB and his victory at Diagonale des Fous in October of 2025. He has also delivered strong results across races in the UTMB World Series, demonstrating consistency and adaptability across distances and terrains. Known for his smooth running style and tactical patience, Chassagne often builds his races conservatively before moving up in later stages. While he is still early in his career compared to established stars, these performances signal his potential to secure major victories in the coming years. With France’s deep trail-running culture behind him, Chassagne continues to evolve into a serious contender at the highest level.

It already seems impossible to run 100 kilometers, much less 171km with over 10,000 meters of elevation gain, and that’s to be taken literally. To anyone “normal”, it’s unthinkable. But for Courtney Dauwalter, Miao Yao, Rémi Bonnet, and Baptiste Chassagne, it’s what they were born to do. It’s where they find meaning and purpose. Their singular mindset is what allows them to find the strength and will to do what anyone else can’t. These four prominent trail runners are now part of the TUDOR family because their mindset is exactly what it means to be born to dare. They’re not just leading trail runners, they’re some of the world’s most elite athletes, period.
