Will someone run a marathon in less than 2 hours (per IAAF rules) by 2023?
The sub-2 hour marathon has obsessed the running community for years.
In 2017, Nike launched an experiment to see whether at least one of 3 elite marathoners might be able to break through this barrier under ideal training and racing conditions. Eliud Kipchoge of Kenya came achingly close, putting up a time just 25 seconds short of the mark.
One line of thinking suggests that, once this barrier is shattered, we’ll start seeing sub-2 hour times crop up regularly. Brad Wilkins, Nike’s director of NXT Generation Research said as much to CNN
We believe that once a sub-two-hour marathon is done, the records will fall at traditional marathons after that… People will run faster and faster, similar to when Roger Bannister broke the four-minute mile."
But maybe this will be harder than the optimists believe. Slate Magazine clarifies the problem:
The size of that gap between Kipchoge’s “theoretically optimized marathon” and the “real world record” tells you one of two things about the future of the marathon, depending on your perspective. Option one is that Kipchoge is so good that he has shown what is truly possible…Option two is the realization that some of Nike’s tactics were so effective that they were worth between two and three minutes to Kipchoge.”
If “option two” is correct, then we’ll probably have to wait a bit longer—maybe a lot longer—before the record falls according to rules defined by the Association of International Marathons and Distance Races (IAAF).
Please note that Metaculus asked a similar question in the past, and it resolved negative. That timeframe was tighter. But still, you've been warned!
Will someone finally succeed in running a sub-2 hour marathon—an attempt recognized as valid and successful by IAAF—before January 1, 2023?
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.
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.
Note: this question resolved before its original close time. You earned points up until the question resolution, but not afterwards.

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.
