A group of skiers climbing the Col du Pacheu during the 69th edition of the Trophees du Muveran, a ski mountaineering race through the Swiss Alps, above Les Plans-sur-Bex, in Switzerland, yesterday. One of the oldest ski mountaineering races in the world, the Trophees du Muveran was first held in 1948. The race takes place along three routes based on difficulty, with the hardest - the Super Trophee - involving a nearly 2,800m descent over 32km. In ski mountaineering, participants climb mountains either on skis or while carrying them, then descend on the skis.
