Taiwan’s Vice President Hsiao Bi-khim congratulated Honnold on the ascent, writing on X: “I admit I would probably feel sick, too, barely able to watch.”
Honnold was greeted at the top of the building by his wife, who expressed concern for the wind and heat as he climbed.
But there was another distraction during his ascent.
As Honnold reached the 89th floor, fans cheered and waved, face to face but for the window with the man clinging to the building.
Video of the moment, external was shared by Honnold and Netflix on Instagram, showing the climber continuing undeterred.
Honnold has made many extreme climbs during his career. A documentary about his ascent of the 3,000 foot (915m) El Capitan, titled Free Solo, won an Academy Award.
