Fueling for the Long Haul: Ultra Nutrition with Mari

I'd love to hear from you. Send me a text

In this full-length episode of Mindful Runner, Fred hosts a live webinar with ultra-runner and Precision Nutrition athlete Mari Marincowitz to unpack one of the most critical — and sometimes overlooked — aspects of endurance running: fueling on long efforts.

You’ll learn:

• What “good fueling” actually means: tailored intake based on effort and duration
• How much to consume per hour to stay energized without overwhelming your gut
• Why practice matters: gut training is just as essential as physical training
• Smart use of real food vs sports gels, especially during multi-hour efforts
• Electrolyte and hydration strategies to support fueling and avoid common pitfalls
• What to do if things go wrong mid-race — and how to adapt on the fly
• Mindset tools for staying calm and responsive when fueling challenges arise

Whether you’re prepping for your first ultra or refining your 100‑mile strategy, this episode delivers practical tips, science-driven insight, and race-tested wisdom to help you fuel smarter — and finish stronger.
