In a record-breaking duel with his Kenyan compatriot Stanley Biwott, Kipchoge clocked an unofficial 2 hours 3 minutes 5 seconds, just outside the world record mark of 2:02:57 held by another Kenyan Denis Kimetto. Kipchoge, who has lost only one of his seven marathons, powered away from New York champion Biwott over the last three kilometres to shatter Kenyan Wilson Kipsang's course record of 2:04:29.
