The People Run Podcast
My name is Fitz Mayi. I’m one of those people who believes you can do anything. Maybe I’m naive, but I’ve seen it in myself and in the incredible people I’ve met. That’s what this podcast is about.
I can’t do it for you but what I can do is inspire. Through wild stories, through experts in the field, and through runners who’ve done it and are doing it now. The road may be hard, but my aim is to shed light on stories of incredible people so you can believe it can be done, and show up for yourself.
Whether you’re working a full-time job, raising kids, chasing a new PR, dreaming of going pro, or building your own transformation this podcast is for you. This is The People Run Podcast: the stories of your incredible self.

Episode 16: Nutrition Myths Busted: What Every Runner Needs to Know with Registered Dietitian Carla Duenas
There’s more nutrition “advice” out there than ever… but how much of it actually helps runners?
In this episode of The People Run Podcast, Fitz sits down with Carla Duenas, a registered dietitian and endurance athlete, to cut through the noise and set the record straight on what really fuels performance.
Carla shares the science and the practical takeaways behind:
- Why carbs aren’t the enemy and how to use them the right way
- The truth about keto, fasting, and other fad diets for runners
- Supplements vs. food first: what’s actually worth your money
- When electrolytes matter (and when plain water is enough)
- Building a balanced plate that supports recovery and long term health
Whether you’re training for your first 10K or chasing a marathon PR, this conversation will help you fuel smarter, avoid the hype, and run stronger.
