ZAHIR | First female ascent of Zahir 8b+ 300m | Katherine Choong

"ZAHIR | First female ascent of Zahir 8b+ 300m | Katherine Choong" is a rock climbing video (29 minutes) published by MAMMUT on July 2, 2026 with 93K views. Available to watch free on CouchClimbs.

Katherine Choong and Eline Le Menestrel set their sights on Zahir, a 300-meter 8b+ multi-pitch line on the Wendenstöcke and one of the most demanding routes in the Swiss Alps. With a bold twist, Eline agrees to join only on the condition that the entire journey be made using low-carbon mobility—arriving by bicycle—layering physical fatigue onto an already serious alpine objective before a single move is made on the wall. What unfolds is a striking portrait of commitment, friendship, and high-end climbing in a breathtaking mountain setting. The tiny holds, the cumulative toll of days on the route, and the weight of a first female ascent make for a genuinely gripping watch. This is a film for anyone who appreciates climbing not just as performance, but as a thoughtful, full-circle adventure.

When Katherine Choong invites her friend Eline Le Menestrel to climb the multi-pitch route Zahir, a classic of the Swiss Alps and the hardest line on the Wendenstöcke, Eline agrees, but only under one condition: to travel exclusively using low-carbon mobility. As the days go by on the wall, they soon realize how ambitious this project really is. The commitment of the route, the tiny holds, and the fatigue from cycling are a real struggle. Despite their motivation and enthusiasm, will Eline and Katherine find their Zahir? #RisewiththeMountain Athletes: Katherine Choong, Eline Le Menestrel Director: Julien Nadiras Music by The Ohohohs and Eline Le Menestrel.
