It's Labor Day weekend in the U.S., and I bet just about everyone could use a day off after this past weekend of racing. The UTMB Mont Blanc festival and its group of races in Chamonix, France, were incredibly exciting and had the world watching. All of those races are highlighted below, as well as a few smaller races happening over the long weekend.
Before the race start, this year's course was originally rerouted near its finish line, between Les Houches, France, and Chamonix, because of landslides on the trail along the Arve River, and then just prior to the race start, the race organization rerouted off an exposed section between La Gittaz and Beaufort, France, 73 kilometers into the race, because of anticipated storms. The new route didn't lose much distance but lowered the total elevation gain and made final race times significantly faster.
