Alex (Alex Honnold) took about 90 minutes — roughly 1 hour and 31 minutes — to climb the skyscraper (Taipei 101) during the recent “Skyscraper Live” ascent.

Quick Scoop

  • The climb was a free solo (no ropes, no harness), up the 101‑storey Taipei 101 tower in Taiwan.
  • Multiple reports note he reached the top “in just over 90 minutes,” with a precise time of about 1:31:34 from ground to summit.
  • The building is around 508 meters (1,667 feet) tall, making this one of the highest urban free‑solo climbs ever recorded.

Why this is trending

  • It was broadcast as a global live special, which added to the drama and attention around how long it would take him to finish.
  • Weather delays and safety concerns before the climb helped build suspense, so the final 90‑minute push became a key talking point in news and forum discussions.

In forum and social chatter, people are mostly zeroing in on that “about an hour and a half” mark, comparing it to big-wall climbs and calling it one of the wildest urban stunts ever.

TL;DR: It took Alex roughly 90 minutes (about 1 hour and 31 minutes) to climb the skyscraper from bottom to top.
