When Katherine Choong invites her friend Eline Le Menestrel to climb the multi-pitch route “Zahir”, a classic of the Swiss Alps and the most difficult route on the Wendenstöcke, Eline agrees—on one condition: they will travel only by sustainable mobility. As the days pass on the rock face, they realize the challenge is ambitious. The commitment required by the route, the tiny holds, and the exhaustion from cycling push them to their limits.
