You know, that is intense, absolutely intense.

And the level of dehydration must be just, yeah, you'd be weeing out all sorts of it.

Well, dust, I would imagine by the end of that.

I'm wearing basically two mattresses strapped to my feet.

I've got a new pair of shoes and they are bouncy.

Yeah, yeah, yeah.

And they do help with the knees and everything because I'm getting older as well.

So you've got to be careful of the joints and everything.

So, yeah, two big bouncy pairs of shoes.

I'm going to disagree with that and just say...

I was talking to somebody about this the other day, about naked running, funnily enough.

And the thing is, you know, with high-tech running gear, it's designed to sort of pull the moisture away from the skin so you stay drier.

But if you've just got sweaty skin on sweaty skin, wherever that may be, whichever bit is touching which other other bit, you will get problems.

And it's things on a long-distance run, little things that you don't think about, like a label in your shorts can just, over time...

You know, take a leg off.

That's a very interesting point.

And I've only found out recently there's a technique of running called jeffing, which apparently is what these hunters used to do as well, which is a combination of run walking.

And it's after a guy called Jeff Galloway, who was an American Olympian.

And it's used by a lot of runners now where you do conserve energy going up slight inclines or to stop long-term fatigue, walk for a bit.

So it's running and walking.
