Switzerland based Michi Wohlleben has made an ascent of Beat Kammerlander's Prinzip Hoffnung at Burs in Austria. The route was first climbed in 2009 and weighs in at F8b/+, making the route roughly equivalent to an E9 or E10.
Wohlleben is an extremely versatile climber having made numerous hard ascents in several diciplines. At the age of 21, Wohlleben became one of the youngest UIAGM mountain guides, he has completed speed ascents of the Eiger North Face, the Tre Cime North Faces, climbed M14, F8c and now an ascent of a notoriously hard E9/10.
Prinzip Hoffnung was one of the crowning achievements of Beat Kammerlander's climbing career. In 2009, Kammerlander commented on the route saying:
"During my successful climb when I reached the crux I had the feeling as if I was constantly falling, I was so surprised that I still stuck to the rock, like a drop dangling under a ceiling. I felt that I was falling but I kept going for it. The primal will that I felt in this situation, coming from deep down in my stomach, is what I remember and what carried me through. When I climb such a route I don't feel like I am 50 years old."
Wohlleben's ascent is the 8th after Kammerlander, Alex Luger, Jacopo Larcher, Fabi Buhl, Babsi Zangerl, Christian Bindhammer and Nemuel Feurle.
