One of the toughest ski mountaineering races is the Patrouille des Glaciers (PDG). It's organised every two years by the Swiss Armed Forces, in which military and civilian teams compete. In takes place every two years by the end of the season in April and goes from Zermatt to Verbier. With #project360 Mammut brings the PDG to your screen with stunning 360 photos.
It's 53 kilometers (as the crow flies) from Zermatt to Verbier via Arolla. You climb around 3994 meters and descend around 4090 meters. This is similar to traveling 110 kilometers without altitude difference.
You need to have quite some skills to compete in this exhausting race. Your physical condition should be equal to an Ironman-Athlete, you need to have some excellent skiing skills and you must know how to behave in the high alpine.
