Show Notes
A single ferritin test isn't the whole story. Coach Nick and Coach Amanda talk with sports dietitian Callie Roseland about the difference between low ferritin, iron deficiency, and anemia, why runners are especially prone to running low, and the ferritin number that actually supports performance versus the number that just clears a lab's "normal" range.
We also cover when to (and definitely not to) get iron labs drawn, how hard training affects iron absorption through a hormone called hepcidin, and why more iron isn't always better.
Guest Callie Roseland, MS, RD, LDN, CSSD, IFNCP, EP-C is a Sports Dietitian who specializes in helping endurance and mountain athletes fuel for performance, recovery, and long-term health. She has 9+ years of experience in high-level performance nutrition, including more than 7 years as a Tactical Performance Dietitian supporting U.S. Special Operations Forces within a multidisciplinary human performance team.
Through her private practice, Fueling Upward, Callie works with adult athletes who lift, run, and climb mountains while balancing serious training with full-time work, family, and real life. Her background in exercise physiology, sports nutrition, and integrative and functional nutrition allows her to take a comprehensive approach to performance, with particular interests in endurance fueling, performance labwork, gut health, hormone health, injury recovery, and optimizing nutrition to support high-level training and performance.
Fueling Upward offers 1v1 virtual nutrition coaching, group education, and on-demand resources to help athletes have more energy, ditch gut issues, and fuel the training it takes to cross finish lines and climb mountains.

Pro marathoner Sara Hall joins Coach Nick and Coach Amanda one week after the Chicago Marathon to talk marathon recovery, motherhood, and her memoir, For the Love of the Grind.
Olympian Carrie Tollefson joins Coach Amanda and Coach Nick days after broadcasting the 2026 Chicago Marathon. Carrie made the 2004 Olympic team in the 1500m, won five NCAA titles at Villanova, and now runs her mouth more than her legs (her words) as a marathon broadcaster and host of the C Tolle Run podcast. In this episode, we cover: • What the Chicago Marathon looks like from the finish line broadcast position • Why Carrie ran three marathons just to commentate them better • The human stories behind Hawi Feysa, Clayton Young, and Vinny Mauri • How to handle negativity and why running needs a “positive thread” • What everyday runners can learn from pros (you deal with the same mile 21) • Running identity after competition, plus balancing career, kids, and 20-minute runs • Prize money, the running boom, and celebrity run clubs • Why success comes from finding your joy, not your finish time • The Secret Interview Questions (and a story her mom will not love)
How long should you rest after a marathon? Coach Amanda (fresh off her fall marathon) and Coach Nick cover marathon recovery from taper week to your first run back.
We did an old fashioned listener Q&A, and because you all sent in a stack of nutrition questions, we called in the big guns: sports dietitian Stevie Lyn Smith, RD, CSSD, back for round two. Coach Amanda and I cover the coaching side while Stevie brings the fueling science. We get into how many carbs per hour you actually need on long runs (and why the answer is a range, not a flex), how to juggle fast 5Ks, marathons, and heavy lifting by building training seasons, and how to keep burnout from wrecking your year. Amanda goes on a legendary rant about lottery FOMO. I explain resiliency data points and why belief beats hard work at your absolute peak. Then we help a first time Philly marathoner avoid the mile 20 wall, dig into the new ASH ferritin guidelines (and why ferritin alone does not tell the whole iron story), and answer the big one: can you safely cut weight before a marathon? Spoiler: Stevie said yes to cutting a bagel. That is it.
Coach Amanda and Coach Nick talk masters running with coach Kim Nedeau (Training Inclined) about how mileage, recovery, and strength work should change after 40, plus what the research really says about bone density, menopause, and weighted vests.
