This unique tour is a chance to experience so much of what the Mont Blanc region has to offer when it comes to trail running!

We’ll start 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 over the next few days will then take us over the border to Switzerland and along the second half of the Tour du Mont-Blanc. We’ll cross Grand Col Ferret and then it’s on to the Alps villages of La Fouly and Trient.

From Trient, we’ll run over Col de Balme on the French-Swiss border, and descend to Chamonix, the world’s epicenter of trail running. No place has more trail running history, or is more alive with mountain runners– and we’ll be there right for all the excitement of the legendary Mont Blanc Marathon series of trail races, which range from 10 km to 90 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,” and we’ll take full advantage, sampling some of 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.

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, we’ll cheer on some of the world’s best trail runners as they arrive in Chamonix.

  • 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.
