Taipei: U.S. climber Alex Honnold successfully ascended Taipei 101 on Sunday, completing the highest-ever urban free-solo in just over an hour and thirty minutes.

According to Focus Taiwan, climbing without a rope, the 40-year-old "Free Solo" icon reached the spire of the 508-meter, 101-floor tower at 10:43 a.m., in the live Netflix special titled "Skyscraper Live."

"This is so cool," Honnold said, after taking a selfie as he stood atop the building's spire. "I'm so psyched. And you know what, pretty tired actually. The whole top of the building is pretty physical," Honnold remarked, adding, "So amazing."
