We’ll start our tour in the rustic Italian village of Courmayeur, on the south side of Mont Blanc. We’ll enjoy a day of trail running along high pastures and through the bucolic hamlets of the Val Ferret, all within full view of the glaciers of the Mont Blanc massif.

Our route will then take us over the border to Switzerland, as we run inn-to-inn along the second half of the iconic Tour du Mont Blanc. We’ll cross the high Grand Col Ferret and descend to the villages of La Fouly and Trient.

From Trient, we’ll run over Col de Balme on the French-Swiss border, and descend to Chamonix, arguably the world’s epicenter of trail running. No place has more trail running history, or is more alive with mountain runners taking in the dramatic views from the home of modern alpinism.

We’ll be in Chamonix for the excitement of the legendary Mont Blanc Marathon series of trail races, which range from 10 km to 80 km. Many of the world’s best trail runners will be on hand. A limited number of race entries are available through Run the Alps.

Chamonix is known as, “La Vallée du Trail,” for its wide variety of trail running opportunities. We’ll sample the best runs, through the Aiguille Rouge nature preserve, onto the high balcony routes on either side of the valley, and even the thrilling “Kilomètre Vertical.”

Typical distances are 6-12 miles, with about 3,000 feet of climbing. Many days include the option to extend or shorten the day, based on personal interests.

After a short climb, we’ll have lunch along the lake in Champex, before tackling the climb up to to Bovine, finishing with a reward of homemade cake and drinks amidst the impressive and hardy Val d’Hérens cows.

At the end of the day, we can wander into old Chamonix to watch some of the best runners in the world finish the tough 80-km ultra race, or tackle the steep Chamonix Vertical Kilometer.

You’ll be on your own tonight for dinner, allowing a chance to wander the pedestrian walking routes of Chamonix and pick one of the many open-air restaurants that fill the village.

For those of us watching, there are great locations to which we can run and cheer on the runners with an “Allez-Allez!” or “Bravo!” In town or high atop Planpraz a thousand meters above town, we’ll watch racers as they finish the course.

Today, you’ll have the option of running the famed Chamonix Marathon.

An option exists to cheer on racers as they run along the scenic Aiguillette des Possettes. We’ll end the day with a celebratory farewell dinner in Chamonix.



  • Refuge des Aiglons
  • Breakfast, trail snacks, dinner

Day 8

It’s time to take leave of the “Valley of Trail Running.” Your shuttle will take you directly to Geneva for the flight home. An option exists to stay additional nights in Chamonix, using Run the Alps’ self-guided materials for additional trail running.

  • Breakfast

Plan to arrive the day your tour starts, at the latest. Note that flights from the US usually arrive on the following day, so schedule accordingly. The closest airport is Geneva, about two hours away. This tour includes individual airport pickup in Geneva.

For those wanting to spend a few extra days in Chamonix, the “Vallée du Trail” with over 500 kilometers of trail running, we can assist in extending your time and providing self-guided trail running materials, either before or after the tour.


Plan your departure for the day the tour ends at the earliest. The Geneva airport is one and a half hours from Chamonix by shuttle, so it’s possible to leave the day the tour ends as long as your flight is not too early. This tour includes return transfer to the Geneva airport. Please discuss options with us if you’re unsure about your departure plans.
