What is the Trail des Aiguilles Rouges?
The Trail des Aiguilles Rouges, often shortened to TAR, is a mountain trail running event held in Chamonix-Mont-Blanc. It takes runners onto the trails of the Aiguilles Rouges massif, the mountain range opposite Mont Blanc.
The event is known for its technical terrain, autumn colours and wide views across the Chamonix valley. The routes are demanding, but the atmosphere is friendly and rooted in the local trail running community.
The 2026 edition includes three race formats, making the event suitable for experienced mountain runners as well as those looking for a shorter Chamonix trail race.

Why the Trail des Aiguilles Rouges is worth seeing
The event has a different feel from the bigger summer races. It is smaller, more local and later in the season, but the scenery is outstanding.
The Aiguilles Rouges sit opposite the Mont Blanc massif, which means runners and spectators often get some of the best views in the valley. In late September, the colours can be beautiful, with forest trails, rocky passages and high viewpoints all adding to the atmosphere.
The finish area around Chamonix gives the day a strong community feel. It is a good event to follow if you enjoy trail running, mountain photography or the quieter side of Chamonix after the main summer rush.
