Estelle Thomas

Kinésithérapeute / Coach sportive

biography

Belgian physiotherapist and sports coach based in the heart of the Alps, I am passionate about outdoor sports and especially trail running. After several road racing experiences, I turned to the mountains and longer distances. My dual perspective as an athlete and healthcare professional allows me to practice thoughtfully, focusing on prevention, adaptation, and sustainable progress. My vision of trail running is rooted in the terrain, authenticity, and commitment.

"Go far, long, and in harmony with your body"
"Run to explore, not to wear out"
"Consistency contradicts what intensity alone cannot sustain"

Landmarks & field tips

En trail, comme dans tous les sports de montagne, la clé est et sera toujours l’adaptation : tant au terrain, qu’à la météo et à son propre état physique. Une préparation cohérente et un équipement efficace permettent d’aller loin en toute sérénité.
