Professional mountaineer Michi Wohlleben faces seventy kilometers and 7000 meters altitude difference of exposed and brittle ridge climbing if he is to cross the entire Wetterstein Ridge without a break. In addition to strength and endurance, mental stamina and concentration are especially important in order to be able to move through this demanding alpine terrain over such a long period of time. For months before the project start, the German undergoes a hard, structured training schedule, learning to stay focused and agile, even when his body is screaming with exhaustion because that is what the Wetterstein Ridge demands of him.
