Sprinting on a running track? Hard enough. Sprinting across a 1-inch webbing suspended 65 feet in the air? Absolutely insane! Don't blink, or you will miss China's Li Liangpeng setting the world on fire at the Highline World Championships in Laax, Switzerland. He blazed through a 60-meter (197ft) line in a mind-blowing 23.05 seconds to capture his first world title.
