Kilian Jornet Explores Fast Acclimatization

Is it possible to climb an 8,000-metre mountain in two weeks? What sort of acclimatization is necessary and how does it affect the body?

These are the questions Kilian Jornet and Emelie Forsberg were asking themselves. To find the answer they set off to climb Cho Oyu (8,220m) in May using a new method of acclimatization that could revolutionize climbing.

As Kilian says: “Although we did reach the summit, for us that wasn’t the important thing. What interested us was to see how we felt after an acclimatization that was totally different from any we’d done before.”

In addition to the climber’s experience, the film features Dr. Daniel Brotons, a specialist in mountaineering medicine, who looks at the expedition from a scientific perspective and what this sort of acclimatization might mean for other athletes.

Meanwhile, the last film in the Summits of My Life project, which covers Kilian’s double ascent of Everest, is in production and should be completed by early 2018.
