Key differences: terrain, duration, and hydration

If you’ve ever struggled with GI issues, hydration confusion, high-carb hype, or figuring out what to eat as an ultrarunner… this episode is going to change everything.

In this conversation, I sit down with Board-Certified Sports Dietitian, endurance athlete, and host of the Eat for Endurance podcast — Claire Shorenstein — to break down the nutrition strategies that actually matter for long-distance runners.

We dive deep into the real science behind fueling, hydration, gut training, electrolytes, and everyday nutrition habits — and Claire shares incredibly practical insights that every ultrarunner needs to hear.

Inside the episode, you’ll learn:

• Why GI issues happen — and the specific steps to prevent them
• How to use sodium the right way (and why many runners overdo it)
• Whether high-carb fueling is right for you — and how to know
• The hydration mistakes causing stomach blow-ups late in races
• What everyday nutrition should look like for busy runners
• How to fuel when appetite is suppressed or your schedule is chaotic
• The truth about supplements — and who actually needs them
• Why foundational nutrition matters more than “sexy” strategies
• How to personalize your fueling using real science, not trends

This episode is PACKED with actionable advice, myth-busting clarity, and ultra-specific insight you can use immediately in your training and racing.

Whether you're brand new to ultras or deep into 100-milers, this conversation will help you fuel smarter, feel stronger, and perform at your best.
