Tour du Mont Blanc Ultra

Experience the entire TMB in only 4 days.

Four days, 110 miles, 33,000 feet elevation gain—the Tour du Mont Blanc (TMB) is a grueling test of endurance and mountain passion. Usually done in 7-11 days, finishing in four needs tough planning, stamina, and boldness.

Starting in Chamonix, steep climbs through quiet forests soon lead to narrow trails by glacial lakes and meadows. During your run you will cross through France, Italy, and Switzerland. As you progress, the trail winds over passes like Col de la Seigne and Grand Col Ferret. Fatigue, weather, and sore muscles challenge you, but stunning scenery and runner camaraderie drive you on.

Nights in rustic huts or alpine villages bring brief rest and hearty food, fueling the next day. The final day is tough but thrilling, descending back to Chamonix where the finish line marks an epic ultrarunner’s achievement.
