Newly crowned American indoor record holder in the 800m, and the first woman ever to break 1:58 indoors, Roisin Willis joins C Tolle Run this week! Roisin is coming off an incredible stretch, racing three times in just ten days: she won the New Balance Indoor Games, shattered the American 800m record, and capped it off with a victory in the Millrose 600m. We dive into her journey into the sport, how she balances life as a New Balance professional while competing collegiately at Stanford, and the highs, lows, and everything in between. Roisin also reflects on her rapid rise and shares the advice she’d give her younger self after everything she’s already accomplished.
