Feeling more fatigued than usual? Struggling through workouts that used to feel easy? If your training isn't matching your effort, low iron could be the missing piece.

In this solo episode, sports dietitian Katie takes a deep dive into one of the most common—and often overlooked—nutrition concerns in endurance sports: iron deficiency. Drawing from both the latest evidence and her own experience as a collegiate runner who battled severe iron deficiency anemia, Katie explains why iron is so critical for performance and how even "normal" lab results may not be optimal for endurance athletes.

In this episode, you'll learn:

• Why endurance athletes are at higher risk for iron deficiency
• The early warning signs that often appear before anemia develops
• Which blood tests to request—and why a CBC alone isn't enough
• Optimal ferritin levels for runners, cyclists, and triathletes
• The best food sources of iron and how to improve absorption
• Common mistakes that can reduce iron absorption
• When iron supplementation is appropriate (and when it isn't)
• Practical strategies to prevent recurring iron deficiency while training

Whether you're training for your first marathon, preparing for an Ironman, or simply wondering why your energy has been lagging, this episode will help you understand how iron impacts endurance performance and what steps you can take to stay healthy and perform at your best.

If you've ever wondered whether your fatigue is "just training" or something more, this episode is for you.
