EP 749: The Pendulum of Running-Lessons from 19 Episodes with Dr. Mark Cucuzzella

Dr. Mark Cucuzzella returns for his 19th visit (first joined us in 2012) to unpack the “pendulum swings” in running— from minimalist to maximal shoes, handhelds to hydration vests, and data-free runs to tech-heavy biometrics. He shares how his natural-footwear ethos (and Two Rivers Treads) started before the trend, why different terrains and athletes may benefit from different shoes, and why rotating options can build stronger, more resilient feet. We talk about rucking with a weighted vest as a low-impact way to boost strength, bone density, and aerobic fitness—especially for masters runners— plus the value of short, fast strides to keep leg speed with age. On fueling, Mark reframes the carbs-vs.-keto debate around individual metabolic health and race-day pragmatism: maintain blood glucose, experiment cautiously, and avoid one-size-fits-all prescriptions. Big takeaway: be an experiment of one—choose the tools, shoes, and fueling that keep you healthy, happy, and on the trails for life.

EP 742: Training the Panic Out: How Astronaut-Level Preparation Builds Confidence on the Trail

What do launching into orbit and starting a grueling mountain ultra have in common? More than you might think. In this episode, we draw from Ryan Holiday’s The Obstacle Is the Way and NASA’s astronaut training to explore how familiarity—not bravado—builds confidence on the trail. Just as astronauts rehearsed every scenario to make the unknown feel routine, trail runners can train for the unexpected: long stretches without aid, bad weather, gear failures, or the mental fog of mile 90. We discuss how to simulate race conditions, build mental protocols for problem-solving, and control the factors within your grasp. By exposing yourself to stress in training—whether it’s night running, solo efforts, or challenging terrain—you build emotional muscle to stay calm when it matters most. The obstacle isn’t the mountain ahead—it’s the panic in your chest, and with the right preparation, you can take its power away. It isn't too late to help out the California Biodiversity Project that Adam is supporting.  All you do is collect soil samples from the trails you are running!
