Hi, I'm Olympian Carrie Tullifson and welcome to the C-Tolly Run podcast.

Today I interview Dr. Jason Karp, an exercise physiologist, coach, author, and runner.

In this episode, we talk about a lot of things, how he got started in the sport and how he made it his career. We talk about the sport at all different levels.

The issues the sport is facing right now with drugs and coaching. The physiology of training and racing,

his nine books in how his tenth is in the works, and the

World Masters track championships. Yep, he's totally trying to get me to do them. So let's get

after it. All right, Jason, thanks so much for coming on the show. Oh yeah, thanks for having having me. Yeah, you and I have been, like, Instagram friends now for a while, like talking about getting you on, and finally we're like, let's just do this. Like, quit putting it off, Carrie, because it's not that I'm putting it off. You always have so much we can talk about, but it's just been busy with, you know, fall races and things like that. And you know how that is. It's just like, come on. Let's have a minute to chat. You're a TV star, Carrie. I can't keep up. I'm not a TV star. But, you know, if they ask me to come and help the sport, I'll do it. And that's how you are. I mean, you know, you have so much of a background in this sport. And I think we want to just chat about that.

But I do think it's nice to hear from a guy who calls himself the running doctor.

But, I mean, somebody that knows the body, knows the sport, knows what, you know, it needs to be fast and fit.

And so we're going to just dig into everything, okay?

Great. So you started running when you were 11. So we're going to go way back then

and start from, you know, ground zero. But when you were 11 years old, you pick the sport up.

What is it about the sport that has kept you? Because how old are you now?

46. So 46. So all of these years, this sport, like, you know, like me, has been the forefront of your life. Yeah. Yeah. Running has been my entire life. I'm very lucky that I've been able to make a career out of it. And it's been my entire life. Yeah. What brought you into it? Oh, well, I just started running as a kid.

I mean, I played a lot of baseball.

The baseball was actually my first love.
