He ran alone as all 4 pacemakers failed to reach 5k at wr pace, then Cheptegei dropped everyone within 10 minutes. He won by 1:30 in front of Abrar Osman. He ran the last 5 slightly downhill kilometres in around 13:10-15 with the last km in 2:27! WOW! If pacemakers would have done their job as planned 40:40 would have been a realistic goal. Joshua Cheptegei, remember the name folks!

Editor's note: The post initially said he ran his last 1k in 2:27. It was 2:37 so we changed the title.
