The Giants' Causeway

In Thueyts, in the heart of the Monts d’Ardèche Regional Nature Park, the Giants' Causeway immerses runners in the wild landscapes of Haute-Ardèche. The trails wind through the forests, valleys and volcanic terrain around the village, with the Gravenne volcano among the highlights. The flagship race, the Three Valleys, takes trail runners on a challenging route through three Ardèche valleys, across wooded paths, ridgelines and mountain trails.
As the route unfolds, the scenery changes but the slopes remain a constant. The race also offers a warm and friendly atmosphere, supported since its creation by a large team of volunteers. Several formats make it possible to take part in the adventure, from a short trail of around ten kilometres to the 51 km course, along with an intermediate 20 km distance. Hikes are also available for those who want to discover the trails without a race bib. A wonderful way to run in Ardèche and enjoy terrain that is as varied as it is hilly!
