UTMB: By the Numbers

Factoids about what many tout as the Super Bowl of Trail Racing, which attracts 10,000 runners to Chamonix, France.

UTMB: By the Numbers Homecountry boy Xavier Thevenard wins UTMB for the third time. Will 2019 bring a record fourth victory?

From August 26 through September 1, a hoard of runners will descend upon Chamonix, France, participating in one of Ultra-Trail du Mont-Blanc’s handful of challenging mountain races. With a long tradition of mountain sports, the intoxicatingly stunning town lies beneath the towering hulk of glacier-capped Mont Blanc, the highest peak in the Alps and flanked by a procession of soaring granite spires. The summit of perhaps the ridge’s most impressive formation, the Aguille du Midi, can be accessed by an improbably steep tram ride right from town.

Surveying the massif with neck craned back, you can hardly fathom that Kilian Jornet has run from the church in the town center to the summit of Mont Blanc—and back—in 4 hours 57 minutes!

Across the valley is the red-hued, snaggle-toothed ridge of the Aiguilles Rouges, capped just above town by the jutting Le Brévent, where an ever-present flock of paragliders soars like colorful vultures. A constant stream of trail runners getting in some last-minute training ascends the renowned Vertical Kilometer route to the Brévent-tram mid-station, a 1,043-meter climb in just 3.5 kilometers. (For us Yanks, that’s 3,421 feet of ascending in just 2.1 miles.)

On scene to document the week’s action, the Trail Runner crew (in partnership with Columbia), including Assistant Editor Zoë Rom, Contributing Editor and Chamonix resident Doug Mayer and Editor Michael Benge, ascended the route’s 78 switchbacks capped by an exposed rock-scrambling section with iron ladders and steps drilled into the rock for added security. On top, the team savored café au laits and then a knee-saving tram ride back to town, where we recovered in a grassy park while watching paragliders come swooping in for landings.

During UTMB week, the town teems with an international throng of trail runners, a scene unlike any in the United States. You don’t feel out of place walking down the busy mall area (cars not allowed) with your hydration vest and running kit. In fact, you’ll likely get passed in both directions by similarly clad runners returning from training runs.

Trail Runner Assistant Editor Zoë Rom and Associate Publisher Ben Yardley get serious with tarts at Refuge du Plan de Laiguille, after a four mile training jaunt with 3,700 feet of climbing the day before running the MCC race.

The energy is town is palpable. Writing this, I was able to watch live video of our Associate Publisher Ben Yardley and Rom bust out of the gate for the start of the MCC via UTMB’s Instagram. Open to race volunteers and workers, the MCC begins in the village of Maligny, and ends—where all the UTMB races do—beneath an arch in the center of Chamonix, next to the church and mayor’s office. The MCC is the shortest of the races, and travels 40 kilometers with a rugged 7,500 feet of climbing.

So, as the tension builds for the week’s other races, here are some factoids we hope will stimulate your interest in this incredible spectacle in our sport.
