Ironically, it took a world record setting run by Kipsang in 2013 in Berlin to beat Kipchoge in what was just his second marathon since moving from the track.
The Kenyan passed through five kilometers in 14:24 and 10 kilometers in 29:21. "But I didn't know I'd run 2:01".
The women's race was understandably overshadowed by Kipchoge's heroics, but 35-year-old Kenyan Gladys Cherono had herself a marvelous day in Berlin as well.
The Olympic champion led a Kenyan 1-2-3 sweep of the podium, youngster Amos Kipruto coming second on his birthday in a time of 2:06:24 while former World record holder Wilson Kipsang finished third in 2:06:48.
Yet even after the last pacemaker peeled off after 25 kilometres, Kipchoge showed no sign of slowing as thousands of Berliners lining the streets egged him on. Just after the 15K mark, pacers started dropping off. Kipchoge was left with Josphat Boit, who owns a personal best of 59:19 for the half marathon, as his lone rabbit.
Kipchoge has earned a reputation as the greatest marathon runner in history, having won Olympic gold in 2016 and this was his seventh Major Marathon title. His second half would ended up being run in 60:33. According to the IAAF, that is the largest improvement on the marathon record since Derek Clayton cut two minutes and 23 seconds off the world record in 1967.
Top put Kipchoge's new time into context, the last time the marathon world record was beaten by over 30 seconds was when Paul Tergat lowered Khalid Khannouchi's mark to 2:04:26. He threw his arms up on his head in disbelief and then jumped into the arms of his longtime coach, Patrick Sang.
A few minutes later Gladys Cherono won the women's race in Berlin in a course record of 2:18:11, making her the fourth fastest woman in history behind Paula Radcliffe, Mary Keitany and Tirunesh Dibaba. Aga came second in 2:18:34 while Dibaba was third crossing the line in 2:18:55.
He added jokingly; "What next for me now is that I have run 2:00, now 2: 01, next is to run 2:02, so that I have all the times in my arms".
"It was really hard, but I was prepared to run my own race early so I wasn't surprised to be alone".
