And of course, if you're running amongst other things, 70, 80, 90 miles a week, it's sort of a bit like feeding machine all the time.

You were running 70, 80, 90 miles a week.

Yeah, yeah, yeah.

So not right the way through the year.

I mean, my mileage in the summer was particularly low, was lower than that because it was the intensity.

So before I broke the mile world record in Brussels...

My last really intensive training session was six by 800 meters with about a minute's recovery.

The average time was 151 and the fastest I ran was 146.

So I knew that I was always conditioned to speed endurance.

And so the whole focus of my training was not mindless mile after mile.

It was, you know, what does each and every one of those miles contain?

Yeah, sometimes I'd go out and I could quite comfortably run 15, 16 miles on a Sunday morning.

But

at key moments of the season it was speed endurance yeah it was the ability to buffer the acid we talked about and it was the physiological response you wanted do you think that we're close to the limits of human potential in athletics distances because surely records can't just continue to be broken i think they will

Look, you know, there's nothing that tells me in civilization, humanity, any, you know, any strata you want to look at that there's a limit to anything.

So I absolutely think that these records will continue to get broken.

And, you know, I also have the privilege of watching athletics, not just at senior level, but at junior and even youth level.

I've just come back from the Caribbean under 20 and under 17 track championships.

The perennial question I get is,

you know, what's, you know, what do you think is going to happen or what do I think would happen when Usain Bolt left the sport?
