"This man," Honnold's friend and fellow climbing star Conrad Anker wrote on Facebook. "Respect. Life goal realized."
After his climb, Honnold told National Geographic that the first challenge was simply to walk up to the California monolith, sit next to the base and put his climbing shoes on.
"Because you look up and go, 'that's a f****** big wall,' " he said. "It's like, pretty crazy."
A lighter moment came later, Honnold said, when he passed some climbers who had spent the night on a ledge. He did his best not to wake them.
"I woke up one guy and he sort of said, 'Oh, hey.' Then when I went by, I think he discreetly woke up his buddies because when I looked down they were all three standing there like, 'What the f***?' "
By conquering El Capitan, Honnold fulfilled a goal he had worked toward for years. He first wrote about the potential record-setting climb in his journal in 2009 — but he repeatedly found reasons to set it aside, as he said last year on the Basecamp podcast with Gripped editor Brandon Pullan.
"Obviously, that's like, the thing to do," Honnold said when discussing El Capitan with Pullan in 2016. "It's always seemed really scary."
Honnold, 31, has become famous for eye-popping ascents that rely on his unique blend of athleticism and mental focus, ascending Yosemite's Half Dome and Zion National Park's Moonlight Buttress. But Gripped says of Honnold's El Capitan free-solo climb, "this is by far the most groundbreaking."
While Honnold said in the podcast that he found the idea of free-soloing the monolith "out of the question," he also told Pullan that he'd been studying it for years and "El Cap is definitely doable."
"I mean, there are two routes that you could potentially do, like Freeride or Golden Gate — they're the two easiest free routes," Honnold said, in a statement that only makes sense coming from someone who's often called one of the greatest rock climbers the world has ever seen.
The challenges on El Capitan, he said, start early, no matter which route you take.
"They all start with Freeblast, which is like a 10-pitch slab," Honnold said, adding that large sections of the granite slab are "basically like walking on a sheet of glass."
The crux of one pitch, he said, is "like this no-hands, foot traverse thing, where you're just like, shuffling across a blank wall."
