We try a higher fat diet and they actually do perform better.

So we stay with that, right?

Like even independent of any metabolic flexibility data we've got in them, great, we're gonna stay in that.

And then we've had others that are the opposite.

So these are these really long, long duration endurance folks that are out there and they just don't do well when the carbohydrates get low.

And so we have to have room for both of those realities.

Some people will perform better on a higher fat diet for more fat oxidizing, lower intensity things.

And some will just do a lot better on those.

And to finish up the point,

I'm talking about long-duration endurance events that are both fast and slow.

So if you look at, to be ridiculous, like we were talking about Cam earlier, you look at some, Rob, producer, these guys are under two-and-a-half-hour marathon times.

Cam's higher, but Rob's a two-and-a-half-hour.

He's fast.

He's going to be burning, I don't know, I don't have metabolic data on him, but 70% to 80% carbohydrate in the marathon.

So that's a long duration endurance event, but that is not a fat burning event.

That is a carbohydrate game, right?

If you want to run a marathon fast, that is a carbohydrate game.

If you want to run a really, really long one and you don't care about speed, you're still going to burn a boatload of carbohydrates.

But now we can afford to go slower with more fat oxidation.

And so when we say endurance, there's also like another level of question.
