About this listen

The conversation of Type-1 Diabetes and Endurance. Redefining what is possible at the intersection of Type 1 Diabetes, human physiology, and extreme endurance. Welcome to The T1Determined Podcast, the definitive audio space exploring how elite athletes, adventurers, and medical pioneers conquer the world’s most grueling physical challenges while managing Type 1 Diabetes (T1D). Hosted by T1D endurance athlete and advocate Joseph Anthony Marcello, this podcast dismantles the historic limitations placed on the diabetes community by merging raw, unfiltered human storytelling with clinical insight. Each episode features deep-dive conversations with ultra-endurance icons—from athletes who have run across continents and through the Sahara, to mountaineers summiting the world’s highest peaks. Alongside these extraordinary individuals, we bring in leading endocrinologists, sports dietitians, and researchers to break down the complex science of managing a chronic autoimmune condition under extreme physical stress.T1Determined™ of T1Determined, LLC © 2026 Hygiene & Healthy Living

  • T1D & Marathons: Mental Fortitude
    May 15 2026

    Today, I talk about my personal journey while training for and running my two marathons. As a T1D, in October 2023, I ran the BayState Marathon in Lowell, Massachusetts. And in September 2025, I ran the Jack & Jill Downhill Marathon in the Poconos, Pennsylvania. Leading up to my first marathon, I discuss the life events that led me to stop drinking alcohol.

    Two and a half years into sobriety, the data is clear—my T1D management and athletic performance are fueled by that one choice. We’re talking about more than just miles today; we’re talking about the mental fortitude and the 'machine' precision required to normalize the movement of not drinking in an endurance culture.

    Whether you're training for your first race or just trying to keep your glucose in range, let’s get to work.

    Poconos Marathon Time– 3:47:34

  • T1D & Sports Performance with Dr. Joe Henske & Lauren Adams, RD of Diabetes Sports Project
    Mar 20 2026

    Today, I am joined by two incredible leaders from the Diabetes Sports Project (DSP): Dr. Joe Henske and Lauren Adams.

    Dr. Henske is a clinical endocrinologist, researcher, and Director of the Diabetes Program at the University of Arkansas, Medical Sciences. Having completed 15 marathons, he is currently leading a groundbreaking study on T1D athletes competing in the Boston Marathon.

    Joining him is Lauren Adams, a Registered Dietitian and Certified Diabetes Care and Education Specialist with nearly two decades of experience blending clinical expertise with a passion for community advocacy– having completed 12 marathons.

    As ambassadors for the Diabetes Sports Project, Joe and Lauren work to empower the millions affected by diabetes, proving through elite competition that proper management and a positive outlook make any dream achievable.

    We dive into the intersection of high-level athletics and diabetes technology. We discuss Dr. Henske’s latest research on marathoners, Lauren’s insights on nutritional victory, and how they are both working to provide the roadmap for the next generation of T1D athletes to perform at the highest levels of sport.
