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.
