2:01:39, and he ran the second half without any pacer. He bested the previous WR from 2014 by 1:14. This was an amazing performance and I'll be surprised if any

2:01:39, and he ran the second half without any pacer. He bested the previous WR from 2014 by 1:14. This was an amazing performance and I'll be surprised if anyone but Kipchoge is able to improve upon it for a long time. (Aside, there's currently a mistake in this article: Last year, on a racecar track in Italy, Kipchoge ran a marathon in less than two hours. No, he ran 2:00:25 there.)
