Kilian Jornet is considered the greatest mountain runner ever, but he doesn’t consider himself a runner. The 27-year-old from the Catalonia region of Spain explains that he uses trail and mountain running as a way to train for skiing and mountaineering during the dry months of summer. Yet, he’s been winning trail races and setting mountain records around the world since 2009. Now the Salomon-sponsored professional trail runner and mountaineer has settled in Norway, where he continues to live and train, and attempts to run and ski the Seven Summits of Romsdalen, a 48-mile route with 9,000 meters of elevation gain, in a single day.
