Happy Birthday, Mary Cain! Here's to the runner who left competitors (and stopwatches!) in sheer disbelief when you became the youngest athlete ever named to a U.S. World Championship team back in 2013. You didn’t just break barriers—you sprinted past them so fast they're still catching their breath!From your historic track moments that inspired countless young athletes, to your continued advocacy for positive change and wellbeing within sports communities today—you're truly unstoppable both on and off the racecourse.
Wishing you joy, laughter, cake-fueled energy bursts—and races won easily enough that you'll have plenty of time afterward for celebration selfies!
