The Fueling Forward Podcast

This episode is an interview with sports dietitian and endurance runner, Claire Shorenstein. Claire grew up not considering herself athletic, mostly focusing on music where she was a high level oboe player. When she decided to join her friend at xc practice one day, she fell in love with running. Claire got her Master's of Music in Oboe Performance at Yale, and after that decided she didn't want to become a professional musician. Her self-described identity crisis led her to do to a year long solo trip in South America, after which she moved to London and rediscovered her passion for running.

While getting into running and training for her first marathon, Claire became interested in sports nutrition. She ended up going back to school to get her Master's in Nutrition from NYU and became a sports dietitian. She opened up her private practice, Eat for Endurance, and became a RED-S informed provider to work with endurance athletes like herself who struggle to meet the demands of training with their fueling.

In this episode, we talk about:

• What it was like growing up involved in music and not considering herself an athlete, then finding cross country and sparking a love for running
• How an identity crisis after getting her Master’s of Music in Oboe Performance and deciding to stop playing the oboe led to a year of solo traveling in South America
• How traveling in a new country helped heal her relationship with food and body image after struggling with an eating disorder
• Why her experience with rediscovering running and getting into marathons inspired her to go back to school to become a dietitian
• How pivoting from road racing to trails and ultras helped her let go of expectations and find joy again in running after burning out from the road scene
• Her experience learning how to navigate fueling and GI issues for longer races
• What types of athletes she works with in her private practice and the most common nutrition challenges she sees endurance athletes face

This episode is an interview with professional runner, Ella Donaghu. Ella grew up in Portland where she was introduced to running through a family of runners. She played soccer as well but ultimately chose to focus on running and ended up becoming a 6x state champion and NXN runner up. She went on to run at Stanford, and struggled initially with her transition after dealing with a stubborn injury, under fueling, and her mental health.

• Her struggles with body image and fueling as she transitioned into her freshman year of college
• How mental health played a role in her struggles with fueling and why seeking help was instrumental to getting back on track
• Her journey from not running a PR since high school to finally having a break through her junior year of college, and what shifts in mindset and fueling allowed her to get back on track and have an incredible collegiate career
• What it was like signing a pro contract with Nike right out of college and why she initially found that transition challenging
• Why it’s important to her to have things outside of running and how that has helped take the pressure off of her pro career

While Maddie is on maternity leave, Alexa Gusman, the newest dietitian at Fueling Forward, is taking over to answer your questions! This episode is a Q&A episode where Alexa answers questions that have been submitted by listeners.

Questions for today’s episode include:

• I’m a high school track athlete, and I’ve found myself struggling with disordered eating. I know I need to fuel my body to support harder training, but anxiety around food, body checking, and nausea/throwing up during workouts have made it really difficult to eat consistently. What advice do you have for getting out of this cycle?
• When trying to establish my typical energy and carbohydrate intake, should I include the calories and carbohydrates from alcohol?
• I’m marathon training and know I need plenty of carbohydrates, but I often feel sleepy after heavier carb-based lunches like pasta and then struggle with my energy in the afternoon. What should a balanced lunch look like to support training while also helping me maintain steady energy throughout the workday?
• Are some protein powders or brands better than others for runners, and what should we look for when choosing one? Is there any meaningful recovery benefit to making your own shake versus chocolate milk or a protein smoothie?
• To Alexa: When in your professional career did you realize it was time to move on from running? And did you always recognize that you might struggle with your relationship with food, or did that become more apparent once you were in school to become a dietitian?

This episode is an interview with professional runner for Nike, Lauren Gregory. Lauren is a Colorado native, where she fell in love with running while out on the trails with her high school xc team. She immediately excelled and after becoming a 7x Colorado state champion and NXN runner up, Lauren committed to the University of Arkansas to pursue D1 collegiate running. Struggles with fueling led to a frustrating injury cycle and she nearly medically retired, but after finding her way back to a healthier version of herself, Lauren had a very successful collegiate career as a 7 time All-American and signed a professional contract with Nike right out of college.

Lauren is now an accomplished track, road and trail athlete having won a US title in the vertical mountain running championships and the 10k trail championships, and making it to the final in the 5k at the 2024 US Olympic Trials. Lauren is also fresh off of her historic win at OCC UTMB as the first American woman to win the title.

In this episode, we talk about:

• How growing up near so many trails allowed her to discover her love for running and what her progression to being one of the best runners in the state looked like
• How trying to eat “clean” and “healthy” in high school led to unintentional under fueling that resulted in two big stress fractures, and her advice for high schoolers struggling with injuries
• Why she doesn’t use a ton of metrics to track her performance and fitness
• How cutting corners with fueling in college led to an injury cycle that nearly caused her to quit running, but instead focused on correcting her fueling and was able to have a successful collegiate career
• Why changing her environment during her transition from college to pro opened her eyes to the importance of fueling, and what she has implemented since
• How the trail running world has changed her view on fueling, and why she thinks fueling is what won her the OCC title
• What trail races are like and why it’s a great options for runners who are feeling burnt out or need something new
• Her breakdown of her win at OCC and how it ended up coming down to a kick in the last 800m
• Why her motto for her training block and race was “don’t wait until you’re hungry”

While Maddie is on maternity leave, Alexa Gusman, the newest dietitian at Fueling Forward, is taking over to answer your questions! This episode is a Q&A episode where Alexa answers questions that have been submitted by listeners.

Questions for today’s episode include:

• I have some abnormal iron and liver panel labs and am cross-training as I recover from an injury. How can I improve my labs to help improve my performance?
• As a healthcare worker, it's not always realistic to fuel every 2-4 hours. How can I navigate fueling when my schedule makes it difficult to do so?

This episode is an interview with physical therapist, Lyndsay Centrowitz. Lyndsay is from Colorado, where she grew up running cross country and track. Her experience with injuries inspired her to pursue a career in physical therapy, and she received her doctorate in physical therapy then went on to practice in a prestigious clinic in Portland that specialized in treating runners. Lyndsay quickly realized there was a gap in women's pelvic health, especially within the context of female athletes, so she became certified as a pelvic floor health specialist. She started her own practice, StrongHER, to help fill that gap in women's health care. She currently lives in Chicago with her two kids and Olympic gold medalist husband, Matt Centrowitz.

We talk about:

• How running injuries in high school led her to working with a physical therapist, which inspired her to pursue a career in the field
• Why she chose sports PT over pediatrics, and how she ended up in one of the most prestigious PT clinics for runners in Portland
• What it was like expanding her practice to include pelvic health, and how that led to her starting her own practice, StrongHER
• How she determined pelvic floor health was a major gap in the PT field, and what the process was like for her to get certified to fill that gap
• Common pelvic floor symptoms in runners that are not normal and might indicate a need to see a pelvic floor specialist
• What a pelvic floor PT does and what an appointment with one might look like
• The role she has seen nutrition play when it comes to physical therapy, especially injury rehab and recovery

I'm back from maternity leave! This episode is a Q&A episode where I answer questions that have been submitted by listeners.

Questions for today’s episode include:

• I have always struggled with needing to go to the bathroom on runs. I have tried eliminating certain foods and even the FODMAP diet which I found to be restrictive. Do you have any reccomendations?
• I’m transitioning from high school to college training and I seem to be always hungry. We also don't practice until 5pm which has made fueling hard. Do you have any tips for managing hunger and fueling for later runs?
• I was diagnosed with osteopenia 2 years ago and even after going through eating disorder recovery and period restoration my follow up scan showed no improvements. Do you have any nutrition tips for building bone?
