Eliud Kipchoge has set his sights on completing a unique set after smashing the marathon world record in Berlin, but his ambition will require him to run slower.
Kipchoge took a minute and 18 seconds off the previous record with his time of two hours, one minute and 39 seconds on Sunday, achieving the biggest single improvement on the marker for 51 years.
The Kenyan has run even quicker in the past, posting a time of two hours and 25 seconds as part of a Nike project that was not ratified by the IAAF.
And Kipchoge, 33, says there is now only one thing missing from his collection.
"I'll tell you what's next for me. I have run 2:00, I have run 2:01. The next [thing for me] is actually to run 2:02 so I have 2:00, 2:01, 2:02, 2:03, 2:04 and 2:05," he joked.
"I lack the words to describe how I feel. It was really hard [during the last 17 kilometres] but I was truly prepared to run my own race.
"I had to focus on the work I had put in in Kenya and that is what helped push me.
"I'm really grateful to my coaching team, my management, the organisation."
