Running a marathon in less than two hours is like going to the moon.
Those were the words of Kenyan athlete Eliud Kipchoge at a news conference in Vienna on Thursday (October 10).
Ahead of his unofficial attempt on Saturday (October 12) to become the first runner to break the two-hour barrier.
(SOUNDBITE) (English) KENYAN RUNNER, ELIUD KIPCHOGE, SAYING: "To run in Berlin and to run in Vienna are two different things.
Berlin is running and breaking a world record.
Vienna is running and making history in this world.
Like the first man to go to the moon.
That's the two different things." The 34-year-old Olympic champion set the world record of two hours, one minute and 39 seconds last September.
Smashing the previous record by a whopping 78 seconds.
He says the upcoming race will be special.
(SOUNDBITE) (English) KENYAN RUNNER, ELIUD KIPCHOGE, SAYING: "And this actually means a lot to my country and my continent Africa.
That it's about actually telling people that there is no one actually who sets the limits.
Only limits are happening in their minds.
It's not actually something tangible, it's just happening in your thoughts.
So what I am doing, is that I'm trying to just remove that click in their minds that no human is limited." A 41-man pacing squad will support Kipchoge during the run.
But the sport's governing body, the International Association of Athletics Federations (IAAF) will not recognize it as an official record, because it is not in open competition and uses those pacemakers.
