862. Roisin Willis, Professional Runner & Stanford University Student

"Sometimes you've just gotta be a little bit fearless." The last time Roisin Willis was on the Ali on the Run Show, the "fastest high schooler in American history" at the time was fresh off earning a gold medal in the 800m at the USA Track and Field U20 Outdoor Championships, and was headed to Stanford University. The two-time NCAA 800m champion opted to forgo her remaining NCAA eligibility in favor of signing a professional contract with New Balance, and she just made her pro racing debut with a stellar indoor season. In this conversation, Roisin talks about racing at New Balance Indoor Grand Prix (she ran and won the 800m), at Boston University (she ran 1:57.97, becoming the first American woman to break 1:58 indoors, and breaking the American record in the event), and at the Millrose Games (she won the 600m). She also talks about her struggles with mental health during her time at Stanford, and about the tools that helped her through the hardest days. Plus, a peek at what's next. (First: midterms!)
