Two Swiss alpinists travel to Kyrgyzstan in the summer of 2025: Gentiana Zyba and Sandra Christen. Khan Tengri has long held their attention—remote, demanding, uncompromising. Together with a local mountain guide, they choose the north side. But high on the mountain, just meters below the summit, the defining question arises: push on, or turn back?
You don't pick your climbing partner based on what the scale says. Whether it's couples, friend groups, or random teams at the gym – most partnerships come with weight differences, sometimes just a few pounds, sometimes way more. It's totally irrelevant in daily life, but when you're climbing, it becomes genuinely important for safety. The weight ratio between belayer and climber directly impacts how a fall gets caught – and that affects the risk level for both people. Here's what you need to understand about why weight matters when climbing, when the difference becomes concerning, and which techniques and tools can keep you safe regardless.

Deep inside the granite cave of Flatanger, Norway, lies a route unlike anything else. Steep, powerful and relentlessly long, B.I.G. 9c (5.15d) stands as one of the most futuristic sport climbs ever bolted.

In September 2024, Mammut athlete Katherine Choong made history in Swiss climbing when she redpointed Zahir (8b+, 300 m), a demanding multi‑pitch route on the Wendenstöcke in the Bernese Oberland, in one day — and she did it in full ecopoint style, which means accessing the wall by train, by bike, and on foot, without motorized transport. This film retraces her adventure and gives voice to Katherine’s raw, personal account of an extraordinary experience. The route spans 300 meters over eight pitches, graded 6c, 8a, 8b+, 7c, 7a+, 7a+, 7b and 6c. Bolted by Günther Habersatter and Iwan Wolf between 1996 and 2004 and freed by them in 2006, it’s considered a benchmark line in the Wenden. The challenge: climb every pitch clean, leading, in a single day.
