The greatest thing about Eliud Kipchoge's World Record today is that his 2:01:39 marathon translates to a 12:41 5000M performance.
His 5000M PB?
12:46.53 ran in Rome on 2nd July 2004, which ranked as no. 4 all-time up until recently, when Barega and Gebrhiwet's stellar runs bumped him to no. 6 all-time.
Think about that for a moment. Over a span of 14 years, he not only managed to translate his track PB to the marathon, but he also managed to produce a much better performance over a distance 8x longer. Perhaps proof that it's possible to get better as you go into your 30s?
By this reasoning, 2:02:57 converts to 12:49. So despite the crazy explosion in marathon talent and the all-out time-trial style racing (which we don’t get much in the 5000 these days), before today no one had run better than 6 guys did in the Paris DL 2012?
It’s hard to know the relative competitiveness of the marathon and 5k, so we can’t make a precise conversion. But I would put Kipchoge today around 12:34; that would put Kimetto at 12:42 and Bekele, Mutai, Kipsang in the 12:42-44 range.
