Trailrunning in Bavaria (Oberland)

Trail running is a popular trend sport in the Oberland (Bavaria). When I was hiking at the Ferchensee near Mittenwald I met some trail runners, and I wondered if they were really running up the mountains. To find out, I went to the Trail Running Trilogy event in Garmisch and interviewed some runners. And indeed - they run up the mountains, but not only, but also walk where necessary, or climb up the path.
