[Download] the Ultimate Guide to Mastering Your Marathon Feeling Strong

Are you unintentionally sabotaging your marathon with fueling mistakes? You're not alone. Most runners over 40 struggle with energy crashes, GI issues, cramping, or bonking — and it has nothing to do with fitness and everything to do with fueling.

In this episode, I'm joined by sports nutritionist, exercise physiologist, and speaker Jenn Giles, who specializes in marathon fueling for masters runners. Together, we break down the most common marathon nutrition mistakes and exactly how to fuel smarter so you can run strong from start to finish.

✅ Here's what you'll learn:

- The biggest fueling mistakes runners over 40 make (and how to fix them)

- Why bonking is totally preventable — if you follow this strategy

- Carb loading mistakes that cause race day disaster (and what to do instead)

- Exactly how many carbs per hour your body needs during a marathon

- Gel vs. chews vs. real food — what REALLY works?

- How underfueling leads to injuries, fatigue, and burnout
