This is a great mini-documentary about an Alpine trail running challenge held in Switzerland that I competed in this past August. The Mountainman is a one-day-race for extreme and endurance sports people whom are strong enough to run on single trails around the BergArena of Unterwalden. The unique route starts at the Mt. Titlis and passes on its length of 80.3 kilometers and 5000 meters of ascent deep blue mountain lakes, wild rock faces and breath-taking views into the high peaks of the Berner Alpen and the beautiful valleys beneath before it ends at the peak of Mt. Pilatus. Check for more info here.
