Aiguilles Rouges Trail

A wild challenge in the heart of the unspoilt nature of Chamonix

The Trail des Aiguilles Rouges (TAR) is a committed race that immerses runners in one of the most beautiful massifs in the Alps: the Aiguilles Rouges. With its technical trails, breathtaking views of Mont-Blanc and crossing of a nature reserve, this trail embodies the pure spirit of alpine trail running.
The atmosphere is both friendly and demanding. There are no frills here: it's all about authenticity, respect for the mountains and pushing yourself to the limit.
