The story

UTMB Mont-Blanc in Chamonix-Mont-Blanc

Each year, Chamonix becomes the base for UTMB Mont-Blanc, an ultramarathon event week centered on trail races circling Mont Blanc through France, Italy and Switzerland. Founded by Catherine Poletti and Michel Poletti and organized by UTMB Group, the event draws more than 10,000 runners; its flagship race is a single-stage roughly 170-kilometer mountain ultramarathon following the Tour du Mont Blanc route, first held in 2003, with the recent edition running August 25-31.

Each August, the alpine town of Chamonix becomes the center of the international trail running calendar as UTMB Mont-Blanc fills its streets, cable cars, and surrounding mountain trails with runners, crews, and spectators from around the world.

What is special

The part that makes it specific.

01

The place changes

UTMB Mont-Blanc's standing comes from being the founding event of what has become a global network of ultra-trail races: first run in 2003 following the Tour du Mont Blanc route, the roughly 170-kilometer flagship race set the template that the wider UTMB Group brand has since expanded internationally

02

The mystery stays covered

Its course crosses three countries, France, Italy, and Switzerland, in a single continuous stage, an unusual feat of logistics and endurance that ties the race directly to the physical geography of the Mont Blanc massif

03

The city starts moving

With more than 10,000 runners taking part across the full event week rather than the flagship race alone, Chamonix transforms for the week into a genuine hub of trail running culture, hosting a spread of races at different distances alongside the marquee ultramarathon
