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 & Kilimanjaro with Katerina Marcello
    Jun 19 2026

    Today, I sit down with my wife, Katerina Marcello. As someone who does not live with Type 1 Diabetes, Katerina represents those who are still affected by T1D, encountering it daily as a support system.

    Together, we recount our recent ascent of Kilimanjaro– at 19,341 ft, the tallest mountain in Africa.

    In early 2026, we trekked via the Machame Route on a seven-day journey to the summit, Uhuru Peak. Having been married recently that November, we indeed did this as our honeymoon.

  • 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.
