Send us Fan Mail Zone 2 training is everywhere—but what does Zone 2 actually mean, and should endurance athletes really build their training around…
Well, that and probably there's others as well that have kind of really...
What's the...
Oh, let me think of it.
Anyways, Maffetone, Phil Maffetone.
Okay.
Also has a lot of, you know, really focuses on like easy zone two running.
So there are others.
And I think some of these philosophies are kind of like, oh, I think that the Phil Maffetone and then there's a whole method that goes with that for calculating zone two.
That particular...
I guess methodology is sort of where I think this like run easy to go fast sort of concept came from.
Because I think a lot of the claims that are made there are that, oh, you know, you run enough in zone two, eventually your resting heart rate will go down and you're going to, you know, your heart rates will come down.
So you can run faster there.
in that same heart rate zone.
Unfortunately, I think there's some, maybe some truth to that, but there's also some kind of myth to that where I think a lot of people have maybe gone down that road and they're, especially if they're new to it, they're maybe getting faster, but it doesn't work forever.
You can't just keep running, running slow and running more and more and more and more in zone two.
And the other problem is there's a limitation to our time.
And I think that's a big piece that I want to bring in here is not all of us have hours and hours to spend in zone two is where maybe we would see some of that sort of benefit.
Like, what if you only have six hours to train? Like, I'm not going to tell that person.
I mean, honestly, probably not going to get the same benefit as if someone had 15 hours to train or something like that.
So we also have to kind of think of it from different perspectives.
But I do.
And it's interesting because I think, yeah, some of like Matt Fitzgerald obviously brings in some higher zone stuff for the 80-20 range.
And, you know, but does that sort of exact, you know, we'll talk about that a little more, that exact percentage.
Is that what everybody should be doing? And I personally don't like to ride my hat on any sort of like...
particular methodology because then you sort of get stuck in that, like, you know, the Phil Maffetone method, like he's now stuck, you know, in that he doesn't, what if he changes his mind or more research comes out and shows us, Hey, actually we don't need to be in zone two.
Well, that and probably there's others as well that have kind of really...
