  1. T1D & Marathons: Mental Fortitude

    May 15

    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.
