What happens, when you are caught by motivation? When your obstinacy drives you to push your limits? How long will you keep up? The German professional mountaineer Michael Wohlleben has set his benchmark high. He wants to traverse the Wettersteingrat non-stop, without a break. 70 km and 7,000 altitude metres on an exposed and crumbly ridge are awaiting him. In addition to strength and endurance, he will need mental strength und concentration, in order to be able to climb for such a long time on such a difficult mountain terrain.
