American rock climber Alex Honnold made an hour-and-a-half "free solo" ascent of Taiwan's Taipei 101 skyscraper on Sunday (January 25) without ropes, watched by thousands of cheering and waving fans as he clambered up one of the world's tallest buildings. Honnold has conquered some of the world's most intimidating rock faces and rose to global fame in 2017 after he climbed Yosemite's "El Capitan", a feat documented in Free Solo. #alexhonnold #taipei101 Subscribe to our channel here: https://cna.
