A Mythical race, a unique experience

From August 27th through September 2nd, the top ultrarunners across the globe rendezvous to Chamonix, France for a week of racing through the Alps. Ultra-Trail du Mont-Blanc (UTMB) is an annual celebration of the ultrarunning community. With breathtaking views across three countries and brilliant runners from dozens more, it’s no wonder why thousands flock to Chamonix during the last week of August each year. The event’s premier self-named race, UTMB, is a 171km race (106 miles) around Mont Blanc with over 10,000 meters of elevation gain (…and that’s just one of the seven mind-boggling races in the entire week.)

GU Crew takes over utmb

The GU Crew usually sends a stacked roster of Team ROCTANE and Salty’s Squad members to Chamonix, and this year is no different. A half dozen of our top ultrarunners have made the trek to test their bodies through some of the toughest terrain and competition in the world.

Who's racing at UTMB?
Patrick Reagan

Patrick Reagan (OCC 55K) – Patrick’s past year has been all-time. He won the 2018 Javelina Jundred and set a PR in the 100K in 6:33:50 (6:20 mile pace for 62 miles.) Patrick is known for speed and endurance, but his 8th place finish at the 2019 Western States 100 Miler shows that he can climb, too.

Keely Henninger

Keely Henninger (CCC 100K) – Keely is running strong again after a couple spring injuries. The 50 Mile US champion recently won the Elkhorn Crest Marathon, proving that she’s ready for a big day. 50-miles and 100Ks are her strong suit, so watch out for Keely as she comes into Chamonix.

Tim Tollefson

Tim Tollefson (UTMB) – He’s got three wins in 2019 alone, including the US 50K championships and the super-competitive Lavaredo Ultra Trail 120K. Tim placed 3rd at UTMB in 2017 and shared the lead with Zach Miller before an injury last year. Like Zach, Tim is certainly a favorite this year. 

Zach Miller

Zach Miller (UTMB) – Zach was leading UTMB at the 120K mark in 2018, but a sudden injury stopped him in his tracks. He’s the first American man to have ever won CCC, and with a top-10 placing in UTMB in 2017, he’s demonstrated that he knows how to handle the Mont Blanc terrain.

Corrine Malcolm

Corrine Malcolm (UTMB) – Fresh off her second consecutive top 10 spot at Western States, Corrine is set for a top finish at UTMB. She had a remarkable 4th place finish at last year’s TDS race, solidifying her spot on the Adidas Terrex World team. Expect to see the biathlete-turned-runner up front.

Paddy O'Leary

Paddy O’Leary (UTMB) – Cancer researcher by day, world-class ultrarunner by night (and into the next day.) Paddy has a 2:20 marathon PR and recently set the FKT for the Wicklow Round on his native Irish land. This will be Paddy’s longest race ever, and we like his chances.
