May 26, 2026
Natalie Rizzo, MS, RD

Whether you’re training for your first 5K or gearing up for a fall marathon, your nutrition needs shouldn’t stay the same throughout your training cycle. In this episode, I’m joined by sports dietitian and former professional runner Maddie Alm to break down exactly how fueling should evolve from base training to peak mileage, taper week and race day.

We cover:

  •  How to adjust your nutrition as mileage increases 
  •  Signs you may not be eating enough during training 
  •  Protein myths for endurance athletes 
  •  During-run fueling strategies and carb recommendations 
  •  What to eat during taper week and before race day 
  •  How to handle low appetite, GI issues and race nerves 
  •  The truth about desserts, supplements and carb loading 

Plus, Maddie shares how she fueled the New York City Marathon, her favorite race-day foods and practical tips runners can start using immediately.

Listen to Maddie's previous episode to hear her story about going from walk-on cross-country to professional runner.
