Discover a trail running experience where the course itself is sculpted by the tides at À Travers L'Estran. This unique and charitable event, scheduled for September 27, 2026, is more than a race—it's a journey across the intertidal zone from the port of La Roche Jaune to the stunning Trestel beach in Brittany. Unlike any conventional trail, runners navigate a wild, ever-changing landscape of seaweed, sand, and rock pools, passing legendary coastal sites like Beg Vilin and the Gouffre. Organized as a solidarity trail supporting the "Enfants de Trestel" and "Ouvrir les Yeux" associations, every step contributes to a profound cause. Embrace the raw, elemental challenge where the rhythm of your run meets the pulse of the Atlantic, creating memories of resilience and breathtaking beauty. Prepare for an adventure that is as much about the heart as it is about the terrain, earning its reputation as a truly unforgettable and philanthropic run.
