It has happened: a man has broken the two-hour barrier in the marathon.

Kenyan marathoner Eliud Kipchoge, the current Olympic champion in the event, just made history on Saturday afternoon (Oct. 12) in Vienna during the INEOS 1:59 Challenge, which was streamed live on YouTube.

The 34-year-old, who is the current world record holder for the marathon set in Berlin last year, ran 42.195km in 1:59:40.

Just how fast is that?

Throughout the entire run, Kipchoge kept to an average pace of 2 minutes and 50 seconds per kilometre.

His slowest kilometre was 2 minutes and 52 seconds.

To give you an idea of how quick that is, he basically ran 3km in 8 minutes and 30 seconds. Or to give you a more relatable distance, 2.4km in 6 minutes and 48 seconds. Or 400m in 68 seconds.

Imagine that speed, but for an entire marathon.

Insane.

But is it a world record? No.

This timing, however, is not counted as a world record because it was not run under normal race conditions.

The run took place in Vienna's Prater Park, and the route involved a 9.6km circuit that involved mostly straight roads.

Kipchoge was also assisted by several teams of rotating pacers in an arrowhead formation.

A support car in front of the pack, which displayed a timer, also projected lasers on the road.

Also, unlike normal races where runners would pick up water bottles from designated stations, Kipchoge had water given to him by cyclists accompanying the pack.

But it's still pretty darn amazing

This is not Kipchoge's first attempt at breaking the two-hour barrier.

In 2017, he ran a 2:00:26 marathon in Monza, which was also not IAAF-sanctioned (meaning that it would not qualify as a world record).

Currently, he is the first man in history to break the two-hour barrier.

After the race, he thanked all his supporters for taking the time to watch this event and said:

"We have made history together, and together we can make this world a beautiful one."

What a champion.
