Salomon athletes Emilie Forsberg and Kilian Jornet are proud to release their documentary film Testing Ourselves about the process of acclimatization that the pair adopted for a recent expedition to the Himalayas. As well as the scientific aspect, the documentary explores the life of the couple during a climbing expedition.

Is it possible to climb an 8,000-metre summit in a fortnight? What type of acclimatization is necessary and how does it affect the body? These were the questions that Jornet and Forsberg asked themselves. In search of the answer, they set off to reach the summit of Cho Oyu (8,220 meters) in the Himalayas using a new acclimatization method that could revolutionize climbing.

In May, Jornet and Forsberg travelled to the Himalayas to attempt the ascent of Cho Oyu. As Jornet 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 experience of Jornet and Forsberg, the film also 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.

Testing Ourselves is both a scientific and a human film. Jornet and Forsberg’s relationship forms a key part of the narrative as, for the first time, the couple talk about what it means to make an expedition together, what the risks are and what it means to them as a couple.

The film is available from today on Jornet’s website and social networks. As well as the video, Jornet explains to users the acclimatization method he adopted for his expedition to the Himalayas.

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