Training day 3: The Breithorn Traverse. We now had passing grades on training climbs at 3,000 meters, now it was time to pass muster at 4,000 meters. The Breithorn traverse is one of the classic climbs in the Zermatt region. At 13,500 feet it follows a narrow ridge line to the side of the Breithorn near it's summit. Here we are on the glacier behind the Breithorn putting on our crampons.
