Welcome to Episode 6 of the Eat for Endurance Podcast, where we dive deep with elite ultrarunner Maggie Guterl - better known as "Maggatron."
Maggie and I crossed paths through Tailwind Nutrition, where she serves as the Athletes & Events Manager. She also leads the Tailwind Trailblazer group, which I joined this year. To be clear, I’m not sponsored by Tailwind, and I’m not receiving any compensation for mentioning them; I just genuinely love their products!
Originally from Pennsylvania, Maggie recently relocated to Durango, CO, the home base of Tailwind. After running her first marathon in 2009, she caught the endurance bug and went on to run her first ultra (a 24-hour race!) in 2011. Since then, she’s conquered numerous 24-hour races, participated in Big’s Backyard Ultra (which she’ll race again this October), and even faced the infamous Barkley Marathons in 2018 - one of the most challenging ultras on the planet! Maggie’s remarkable achievements include a 2nd place finish at the 2016 Georgia Death Race, earning her golden ticket to the Western States 100, where she went on to place 8th female.
In this episode, we discuss how she made the shift from bartending and partying to ultrarunning, how she fine-tuned both her everyday and sports nutrition, and—surprise!—how it is possible to run long distances without feeling like you’re going to puke your guts out.
UPDATE: Maggie just WON Big’s Backyard Ultra! As in, she was the last person standing, running an incredible 60 hours straight. You can read all about her winning race and the nutrition strategy that powered her to victory here.
Tune in to hear Maggie’s inspiring journey, valuable nutrition tips, and why ultrarunning truly is a mental and physical adventure!

Athlete Nutrition Profile - Strength Running Podcast Host & Coach Jason Fitzgerald
Want to get in touch? Send Claire a message!
Welcome to Episode 5 of the Eat for Endurance Podcast, featuring Jason Fitzgerald of Strength Running.
Jason and I met back in 2015, when he moderated a nutrition panel I was on at an Endurance Sports conference. We kept in touch thereafter, and I was excited to be a guest on his new at the time podcast to talk all about the impact of pregnancy on running and nutrition, towards the end of my first pregnancy (listen to the episode here). So now it’s Jason’s turn to talk all things nutrition and running!
A little background on Jason - he’s an accomplished runner, a USA Track & Field certified coach, founder of Strength Running (one of the largest running blogs on the web), author of 101 Simple Ways to be a Better Runner and Running for Health and Happiness, and podcaster (his guest line-up is amazing - check it out) as well as a father of three young kids, based in Colorado.
I think you’re really going to enjoy our discussion about his nutrition and athletic background, how Strength Running came to life, how his diet and approach to nutrition have evolved especially since working on his own Nutrition for Runners Program with fellow RD Anne Mauney, and balancing his own training and professional life with raising young kids.

Fueling Young Athletes - A Discussion with Sports Dietitian Lauren Antonucci
Want to get in touch? Send Claire a message!
Welcome to Episode 7 of the Eat for Endurance Podcast, featuring Registered Dietitian Lauren Antonucci. Today’s topic of fueling young athletes (i.e. through the collegiate level) is one that I am particularly excited about, as I love working with this client population, and as a parent myself, hope to raise my girls to enjoy physical activity as much as my husband and I do!
Lauren is the perfect person to talk about fueling young athletes, both from a personal and professional standpoint. She is a longtime runner and triathlete with thirteen marathons and three Ironman races under her belt, a Mom of three active children, and a sports dietitian who has extensive experience with both adults and younger clients (her additional specialties include diabetes and eating disorders, among others). Lauren is the director of Nutrition Energy, a Manhattan-based private practice where I have been freelancing for the past few years. If you need a dietitian for yourself or your child (especially while I’m on maternity leave), reach out to the office to work with Lauren or another RD on staff and please mention that you were referred from this episode.
Here are some of the things that we cover in our discussion:
- Personal experience as dietitians and athletes with raising active, healthy kids
- Role modeling healthy behaviors as a parent
- Making food and exercise fun and appealing
- Balancing treats with other foods to foster a positive relationship with food
- How parents can encourage optimal fueling for performance while still allowing their kids to enjoy being kids
- Nutrients that we keep a close eye on with young athletes
- Navigating body image and disordered eating issues, should they arise
- Red flags parents can watch out for re: underfeeding and disordered eating
- Handling scheduling challenges from a nutrition perspective, including travel to practice, games, camps, races, etc, especially with rigorous academic schedules
- Addressing a child’s desire to follow a restrictive diet (e.g. vegan or vegetarian)
- Fueling adequately within the team environment, especially if the environment is not conducive to eating/drinking
