2021 UTMB Live Coverage

Altra Lone Peak 5 MenFor the 11th edition in a row, iRunFar is covering UTMB! The UTMB course is 171.5 kilometers (106.5 miles) long with over 10,000 meters (32,800 feet) of climbing, and it encircles the famed Mont Blanc, starting and finishing in Chamonix, France, while traveling through Italy and Switzerland in the process. The race starts at 5 p.m. CEST (9 a.m. MDT in the U.S.) on Friday, August 27.

You can find our full news stream of the event in this article as well as more resources to help you follow the race. You can also venture over to our Twitter feed for in-depth coverage from the course during the race.

The course records are held by Rory Bosio at 22:37:26, set at the 2013 race, and François D’haene at 20:11:44, set in 2014. Keep in mind that the race increased in length by a couple (very difficult) kilometers since these two records were set, so someone will have to have an incredible day to get under these times. But, this is 21st-century ultrarunning and someday in the not-too-distant future a runner will.

A special thanks to Altra for making our coverage of UTMB possible!
