Conquering this 14.3 mile hiking trail in Germany is no easy feat, and doing it at a fast pace makes it even more difficult! The trail is called the Watzmann-Überschreitung loop (try saying that three times fast), and getting through it usually takes about two to three days. However, Philipp Reiter filmed his friend Anton Plaze crossing the rough terrain so swiftly that he finished it in just under three hours!
