So even the organisers didn't anticipate that this could happen because they set the pacemaking out to be at two hour and one minute pace at halfway.

So they set a 60 minute, 30 second pace for the pacemakers out front, pulling them, Sebastian, that way along.

And then at that point, he accelerates off that to run the second half of the race, a half marathon in 59 minutes and one second, which was a minute and a half quicker than the first half of the race.

And the first half of the race had been set by pacemakers who all dropped out.

Like it is to some degree otherworldly in terms of what he did.

And David's right.

The athletes behind him, Yomif Kijelke and Jacob Cablimo, they're highly proficient track runners.

who are chasing Sawe, who's really just a diehard marathon runner.

He's a good track runner, but these guys behind him are now probably going to take this record into the 159 territory and possibly breaking it.

What we're seeing here is 72 years ago, the four-minute mile was broken by Roger Bannister, the greatest barrier in athletics at that time.

And since then, this is the next great barrier to be broken.

And after this, actually, the women's four-minute mile is the next great barrier to be broken.

But this one is extraordinary in lots of ways.

But big caveat.

The technology in science of marathon running has gone leaps and bounds, literally, figuratively and literally, in the last 10 years because super shoes were introduced in 2016.

Nike put all the research and development into them, and now Adidas have perfected them.

All three, one, two, three yesterday, were all wearing the new version of the super shoes.

Now, by super shoes, I mean these are heavily...

high-tech foam rebound effect shoes.

Each of them weighs less than a smartphone.
