Welcome to the Running Explain podcast. I'm your host, Elizabeth. I'm a marathoner, coach, and answer seeker.

When I first started running at the age of 29, I had so many questions and what felt like nowhere to turn to for answers.

And now I'm here to answer all your running questions about anything that you might want to know.

If you're a new runner or you've been doing this for a long time,

there's always something more to learn about running. So let's get started. My guest this week is

sports dietitian and ultra endurance athlete Kylie Van Horn of Fly Nutrition. You may remember Kylie

from her appearance back in season two when we talked about training for ultra endurance events,

especially with an emphasis on how the heck

to fuel those ultra endurance events. And this week, she is back to talk about one of her favorite

topics, gut health for endurance athletes. What does it mean to have good gut health? What is an acceptable

number of bathroom stops on your long run? And what are the signs that

something's really not working in your favor? And it might be time to seek some outside counsel

to get your gut health back in order. The reason you should care about your gut health goes

beyond the inconvenience factor of having to make multiple bathroom stops on your runs or in a race

and goes to, are you absorbing micronutrients correctly? Are you able to tolerate and handle the fuel and fluids that you need to fuel your best races and just training runs in general?

Gut health is really where it all starts because that's where we absorb the things that we need to function,

not just as athletes, but also as human beings.

Kylie, welcome back to the show. I'm excited to have you here.

Yeah, I'm super excited to be back and we're going to be chatting about a different topic today

that I'm really passionate about with endurance athletes.

So you were a guest on the show last year, last season,

talking about ultra training and specifically fueling for ultra endurance.
