Kipchoge maintained his form well in the closing stages to smash compatriot Kimetto's previous best.
The marathon is officially his alone, by a long shot, and now that the final piece of his greatest-of-all-time puzzle is in place, Eliud Kipchoge can enjoy the view from the top.
You'd have to go back 50-years to find a single bigger world record leap than Kipchoge's this weekend.
Kipchoge, 33, broke the record set in 2014 by Kenya's Dennis Kimetto by 1 minute, 18 seconds. "That's what pushed me in the last kilometres". His face never showed any signs of fatigue or worry and by the Half Marathon point, he had run in 1:0046.
He has now won 11 out of 12 marathons he raced in, including at the Olympics.

I will say this. "I doubt it will completely change the incentive-cost-benefit analysis of the other side". The order, according to administration officials, is broad in terms of who and what can be sanctioned.
With weather conditions flawless and virtually no wind, it was clear after the opening few kilometres that Kipchoge's only opponent would be the clock and his three pacemakers were pushed to the limit to keep the tempo high as Kipchoge dipped well below world-record time by the halfway mark.
Kipchoge ran 5km in 14:24 - which was 1:26 faster than world record pace - and passed under the 10km barrier in 29:01.
Berlin debutant Amos Kipruto came second in 2:06:23, followed by a third Kenyan, former world-record holder Wilson Kipsang, who was 25 seconds behind. "That's what pushed me in the last kilometres", added Kipchoge.
Acclaimed as the greatest marathon runner of the modern era, Kipchoge has dominated marathon racing since making his debut in Hamburg in 2013 after a successful track career that saw him win world gold and silver (2003, 2007) in the 5000m and Olympic silver and bronze (2008, 2004) over the same distance. A year ago he set the fastest ever time over the marathon distance on the Monza race track in Italy for Nike's Breaking2 project.
