Jost Kobusch: Choosing the Hardest Line

Jost Kobusch is a German alpinist whose work is defined by a rare commitment: climbing alone, in winter, without supplemental oxygen, on some of the world’s most demanding mountains. His long-term focus is Everest’s West Ridge—a route where isolation, wind and exposure turn every metre into a decision.

For Jost, the mountain is not a stage for quick victories. It is a place to test preparation, patience and self-reliance. While many Everest expeditions take place in the busy spring season with fixed ropes and extensive support, he deliberately chooses the coldest, quietest time of year and a lightweight alpine style.

His Everest project began with exploration rather than a simple summit chase. During his first winter attempt in 2019/20, he reached the West Shoulder at about 7,366 metres; weather stopped a later attempt well below his target. Each return has added knowledge of the terrain, conditions and the limits that must be respected.

In late December 2024, Jost pushed solo to 7,537 metres on Everest’s West Ridge, exceeding the 7,500-metre mark he had set as his objective. He climbed from his high camp in a single alpine-style push, then chose to descend safely rather than force the mountain to give more.

That decision says as much about Jost as the altitude does. Ambition matters—but judgement matters more. In an environment where weather can erase plans in minutes, success is not only reaching higher; it is returning with the experience to continue the project another day.

His path has been shaped by the same independent spirit for years. At 21, he became the youngest person to solo Ama Dablam, and in 2023 he made a solo winter ascent of Denali via the Messner Couloir.

Jost represents a different kind of explorer: focused, patient and willing to work towards a goal over many seasons. His story is not about conquering Everest. It is about pursuing a line that demands total commitment—and staying true to it, one careful step at a time.
