To me this quote is the best gauge of how incredible of a human feat this was.
"One way to measure the greatness of any sporting achievement might be to consider the amount of time that passes before it’s achieved again. New world records are set in virtually every single Olympics. Every year brings new sports stars who stand on the shoulders of those who came before them. Look at someone like Usain Bolt, who has a dominant record in the 100-meter dash that might last for generations. The difference is, lots of people can run the 100 meters (albeit not quite as fast as Bolt).
Honnold, meanwhile, is performing in an event that no one else is even qualified, much less willing, to participate."
