    Episode 29. Iron Deficiency In Endurance Athletes: What You Need to Know

    Iron Deficiency in Endurance Athletes — What You Need to Know Somewhere along the ultramarathon journey, host Erin Quinn lost sight of one crucial metric: iron. In this episode, she dives deep into iron deficiency and iron deficiency anemia among endurance athletes — especially female runners, up to 45% of whom may be affected. Erin breaks down why iron matters (hint: it's tied directly to oxygen delivery and performance), how endurance training accelerates iron loss through hemolysis, sweat, and inflammation, and why menstruating and plant-based athletes face even greater risk. She also shares her own wake-up call — a summer of unexplained fatigue, heart palpitations, and hills that suddenly felt impossible — that led to a shocking blood test result. You'll learn the symptoms to watch for, the difference between iron deficiency and iron deficiency anemia, how it's diagnosed, and what treatment options (from dietary changes to supplements to infusions) look like. Knowledge is power — don't let iron be the blind spot in your training. Start where you are, but make sure you start.
