The T1Determined Podcast

Joseph Anthony Marcello

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.

    Today, Chris and I sit down with Charlie Hurst—British ultrarunner, chiropractor, and endurance coach living with Type 1 Diabetes. After picking up running during lockdown, Charlie quickly went from road marathons to conquering some of the world's toughest ultra-endurance races, including becoming the first British woman with T1D to complete the 155-mile Marathon des Sables in the Sahara Desert. We talk protocols, actionable items on managing blood sugars, and pushing human limits, as well as how she's empowering other T1D athletes to perform at their highest level.

    Type 1 Trail Talks with Mary Beth Cooley

    Welcome to Type 1 Trail Talks of The T1Determined Podcast. Today, I sit down with Mary Beth Cooley. Diagnosed with T1D in her late 30s —just one week before the world shut down for COVID-19— Mary Beth chose to face a daunting new reality with incredible focus. While the rest of the world ground to a halt, she got to work mastering her health. We dive into what it was like navigating a fresh chronic illness during a global pandemic, and how a profound shift in perspective allowed her to see lockdown not as a detour, but as a rare window to focus on herself. That resilient mindset ultimately led her to the trails, and six years later, to our first Project InsulNation trip. – As we build this podcast from the ground up and face every slope head-on, your support is crucial for our continued growth.

    T1D & Marathons: Mental Fortitude

    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.
