    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 & Kilimanjaro with Katerina Marcello

    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. – 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.
