Trail Aiguille Rouge 2025

Trail Aiguille Rouge – A Spectacular Alpine Running Challenge

The Trail Aiguille Rouge is one of the most exciting trail running events in the Alps, taking place in the breathtaking setting of the Chamonix Valley. Runners from across the globe gather here each September to test their endurance on high-altitude courses that combine technical mountain paths, steep ascents and panoramic views of the Mont Blanc massif.

The event offers several race formats to suit different abilities, from shorter but demanding trails to the longer flagship race that climbs towards the Aiguille Rouge itself. Each route showcases the incredible diversity of the Alpine terrain – from forests and rocky ridges to open meadows – making it a favourite for both athletes and spectators alike.
