About The T1Determined Podcast

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.

episode T1D & Marathons: Mental Fortitude artwork

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. BayState Marathon Time– 3:52:08 Poconos Marathon Time– 3:47:34 – As we build this podcast from the ground up and face every slope head-on, your support is crucial for our continued growth. Wherever you're listening, please share this episode and others with anyone you think might benefit.

En fantastisk app med et enormt stort udvalg af spændende podcasts. Podimo formår virkelig at lave godt indhold, der takler de lidt mere svære emner. At der så også er lydbøger oveni til en billig pris, gør at det er blevet min favorit app.

Rigtig god tjeneste med gode eksklusive podcasts og derudover et kæmpe udvalg af podcasts og lydbøger. Kan varmt anbefales, om ikke andet så udelukkende pga Dårligdommerne, Klovn podcast, Hakkedrengene og Han duo 😁 👍
Podimo er blevet uundværlig! Til lange bilture, hverdagen, rengøringen og i det hele taget, når man trænger til lidt adspredelse.
