If you’re training hard but still feeling tired, plateaued, or struggling to race your best, your nutrition may be the missing piece.
In this episode, I’m joined by registered dietitian Alex Larson, RD, to break down how runners can use nutrition as a performance tool — not just something to think about after a workout. We talk about the most common fueling mistakes endurance runners make, how to tell if you're under-fueled, and what “eating enough” actually looks like when you’re training for a marathon or half marathon.
Alex explains why intra-run fueling matters, and how nutrition directly affects recovery, intra-run gel intake, and long-term performance.
If you’re chasing a breakthrough race — whether that’s a PR, a marathon goal like sub-3, or simply feeling stronger and more consistent in training — this conversation will help you understand how fueling properly can unlock your next level.
