When will a climber beat Alex Honnold and Tommy Caldwell's record for climbing the Nose of El Capitan?

In 2017, maverick climber Alex Honnold shocked to world by becoming the first person ever to free solo the ~3,000 foot El Capitan in Yosemite. According to reports, it took him a little less than 4 hours to complete the journey--without any ropes or safety harnasses.

National Geographic called the feat "the moon-landing of free-soloing" and reported:

It’s hard to overstate the physical and mental difficulties of a free solo ascent of the peak, which is considered by many to be the epicenter of the rock climbing world. It is a vertical expanse stretching more than a half mile up—higher than the world’s tallest building, the Burj Khalifa in Dubai. From the meadow at the foot of El Capitan, climbers on the peak’s upper reaches are practically invisible to the naked eye.

In June 2018, Honnold returned to the scene of his triumph. He joined forces with fellow climbing prodigy, Tommy Caldwell, to take the Nose of El Capitan--this time with safety gear--and broke the 2 hour mark, finishing in just 1:58:07.

Hans Florine, who set a record for ascending the Nose in 2002, said of Honnold and Caldwell's feat: "It’s like breaking the two-hour marathon barrier, but vertically,”

Per National Geographic:

The Nose is widely considered the greatest big-wall climbing route on Earth. It runs straight up the prow of the massive granite formation known as El Capitan and is the monolith’s most recognizable feature. Every spring, it draws the world’s most adventurous climbers to test their mettle. Most take three to five days to scale the challenging terrain, “camping” on the wall in portaledges anchored to the stone. For elite climbers, the time to beat is NIAD, or Nose-in-a-Day, climbing it all without an overnight.

According to official record keepers, when will someone (or some climbing team, including possibly Honnold and/or Caldwell again) scale El Capitan in less than 1:58:07?

Metaculus help: Predicting

Predictions are the heart of Metaculus. Predicting is how you contribute to the wisdom of the crowd, and how you earn points and build up your personal Metaculus track record.

The basics of predicting are very simple: move the slider to best match the likelihood of the outcome, and click predict. You can predict as often as you want, and you're encouraged to change your mind when new information becomes available. With tachyons you'll even be able to go back in time and backdate your prediction to maximize your points.

The displayed score is split into current points and total points. Current points show how much your prediction is worth now, whereas total points show the combined worth of all of your predictions over the lifetime of the question. The scoring details are available on the FAQ.

Note: this question resolved before its original close time. All of your predictions came after the resolution, so you did not gain (or lose) any points for it.

Community Stats

Metaculus help: Community Stats

Use the community stats to get a better sense of the community consensus (or lack thereof) for this question. Sometimes people have wildly different ideas about the likely outcomes, and sometimes people are in close agreement. There are even times when the community seems very certain of uncertainty, like when everyone agrees that event is only 50% likely to happen.

When you make a prediction, check the community stats to see where you land. If your prediction is an outlier, might there be something you're overlooking that others have seen? Or do you have special insight that others are lacking? Either way, it might be a good idea to join the discussion in the comments.
