Trail Race in Chamonix, France

Trail run around Chamonix, France, the world’s trail running capital, and take part in one of the six races of the Mont Blanc Marathon series. It’s one of the most exciting times of the year to be here in the home of Run the Alps!

Working in partnership with Mont Blanc Marathon race organizer Club des Sports, Run the Alps has developed a unique package: a chance to spend a week exploring this legendary region of the Alps– and the opportunity to take part in one of the world’s best known trail races. Most of the races sell out quickly, and sign-up for the 23km and 42km distances is by lottery. However, Run the Alps has a limited number of race entries available. (Please contact us for the latest availability.)

The Mont Blanc Marathon races kick off peak trail running season in Chamonix, with 10,000 runners from around the world taking part in the Vertical Kilometer, 10km, 23km Cross du Mont-Blanc, Salomon Golden Series 42km Marathon du Mont-Blanc, or the epic 90km race.

This is a great way to enjoy trail running in the Chamonix region and experience a classic Alps trail race, too!

Chamonix is the home of Run the Alps, so our staff will be on hand, and will join each of our self-guided guests for a visit in town, and a chance to review your plans for the week, discuss race preparations, and answer any other questions you might have.
