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.
