Kilian Jornet didn’t mean to become one of the greatest mountain runners in the world–he was just training for ski season. Salomon TV follows Jornet’s journey as he attempts Norway’s infamous Seven Summits of Romsdalen, a grueling route combining mixed climbing, trail running and ski touring . Considering Jornet finishes the Seven Summits’ 48 miles and 30,000 feet of ascending in less than 24 hours, we’d agree on the “greatest” designation.
