Eliud Kipchoge ran an astonishing world record in marathon in Berlin today. The Kenyan clocked 2.01.39 ( two hours, one minute and 39 seconds) on 42,198 km and was the first man to run under 2.02 ever. He beat his compatriot Dennis Kimetto's erlier world a record - also set in Berlin in 2014- by one minute and 18 seconds.
On thing that makes his achievement even more remarkable is the fact hat he had to run the last 17 kilometres alone after his pacemakers dropped out early.
To get a understanding of how fast this really is you could compare the pace with a cooper test (12 min). 2:01:39 pace means Kipchoge ran 10 cooper tests at a result of 4200 meters- in a row . If you want to translate it to for various distances it 's like this:
If you were to run alongside Kipchoge, how long would you last? On a good day I could last for 800m - 1 kilometre, maybe.
