You may know Alex Honnold from the sensational documentary Free Solo, where the climber completes a lifelong dream to scale the famous El Capitan in Yosemite, California.
Honnold shot to fame after climbing the 3,200ft vertical rock formation and is back for what promises to be another terrifying feat. This time he will attempt to scale the 1,667 feet tall Taipei 101 skyscraper, one of the tallest buildings in the world. The challenge will not include ropes or safety nets, though Honnold has 30 years of climbing experience.
