The 2025 UTMB is here! We can't believe it, but this is iRunFar's 15th year covering the race. This year, the UTMB course is 174 kilometers (108 miles) long and gains almost 10,000 meters (32,500 feet) of elevation as it encircles the Mont Blanc massif from Chamonix, France, through Italy and Switzerland, before finishing back in Chamonix. The race starts at 5:45 p.m. CEST (9:45 a.m. MDT in the U.S.) on Friday, August 29.
