Eliud Kipchoge views his sub-two hour marathon attempt next month as akin to taking a giant leap for mankind – or in the case of the Kenyan runner, make that over tens of thousand of steps for mankind.

Two years ago Kipchoge – assisted by a lead car and 30 supporting pacing runners – set the fastest ever unofficial marathon time of 2:00:25 on the Monza motorsport track In Italy.

In October, Kipchoge will once again attempt to run a sub two-hour marathon at the INEOS 1:59 Challenge in Vienna – on a six mile flat stretch of tree-lined avenue that the runner will cover 4.5 times – a feat he likens to man “standing on the moon.”

“I think it will be on the same place as standing on the moon, going up the tallest mountain or going into the middle of the ocean,” Kipchoge said from his training camp in Kaptagat. “This is another historic moment in sport.

“There is making history and there is making a mark on the sport. It’s like the first man to go to the moon. To be the first man to run under two hours, it’s critical.”
