Watch David Lama and Katherine Choong on Classic Supertramp

David Lama and Katherine Choong climb the classic Supertramp in the Glarus Alps in Switzerland. The 400-metre 5.11 on the north face of the Grosser Bockmattliturm was first climbed in 1980 by Martin Scheel and Gregor Benisowitsch in 1980.

Supertramp has its reputation for a reason: few bolts, and techy slab climbing kept me on my toes. Stay tuned for the #classics video!
