So they discovered the biochemical basis for the wall.

And the last thing to mention is lactate.

This stuff builds up in your muscles.

And it's lactate that makes you feel pain, by the way, after you stop exercising and the stiffness.

And lactate is a byproduct of the glucose being burned.

It's like an exhaust coming off, I suppose.

That can build up and cause pain and soreness.

The more you train, the lower the lactate.

So you keep burning the lactate away and lactate levels are kept lower.

And therefore, you don't feel quite so stiff and sore afterwards.

Although anybody running the 10K, they will feel a bit stiff and sore afterwards because you can't avoid the lactate.

But certainly with training, that's why training is very important.

One of the big effects is you get better able to handle lactate.

lactate coming off the glucose, as I say, as a kind of a byproduct from the engine burning, as it were.

You can keep lactate levels low if you train, and then you're probably going to be okay.

And then lastly, and not least, and I've mentioned it a few times, it's all about the brain as well.

And exercise and training means you'll feel less fatigued because the brain adapts.

The VMH, as I mentioned, isn't it great?

And the psychology of this is important as well.

You're in the zone, you know, you get running and then you're prepared for this, I suppose, psychologically as well.
