A visitor's first view of Chamonix makes the town, situated at the bottom of a tight valley in the Alps at the foot of Mont Blanc, seem impossibly perfect. Classic alpine architecture, a backdrop of meadows and glaciers, epic trails visible from the town square. It all feels fictional. It's the kind of place that tempts you to give up your life back home to figure out how to make it all work here.
But when I arrived in the valley for the first time this past August, my first thought was, Why am I here? To write an article about the Ultra-Trail du Mont-Blanc (UTMB), the 106-mile trail running race that coincided with my visit, sure. To test shoes and join other media in recording the spectacle. But what about me, specifically: What set of circumstances led to this?

UTMB was created in 2003 by Catherine and Michel Poletti as a single 170-kilometer loop around the Mont Blanc Massif, through France, Italy, and Switzerland. But the trails it's held on are ancient. Celtic and Gallic tribes utilized them, and later local shepherds moved their livestock through high mountain passes on them, soldiers marched on them, and now hikers all over consider the Tour du Mont Blanc to be one of the world's bucket list backpacking trips. So many lives, so many steps, so many people looping these giant mountains.
UTMB has become the premier trail running event in the world. During race week, Chamonix and the nearby towns swell with runners and race spectators. The event turns everyone into a runner—it’s infectious; you get here, and you suddenly want to know everything about the event. In the event's first year, just over 700 people toed the start line and only 67 finished. Of those 67, seven women made the full loop, including the first American winner, Kristin (Krissy) Moehl, who finished 24th overall in 29 hours 38 minutes and 24 seconds.
Dropping into the spectacle of what UTMB has become today, with more than 2,000 runners in the main event—not to mention a series of other trail races that occur throughout the week—brand activations, product drops, nightly parties, and all the rest, this history felt important. With so few women participating, Moehl's triumph felt like more than a race win; it felt like the first brick in the foundation of something colossal. But I had to see what UTMB was all about firsthand to understand what's been built on top.
