Ultramarathon trailblazer Courtney Dauwalter joins Laughter Permitted to talk about how she got into running ultras, what went into winning three 100-mile races in the span of 10 weeks and how she reframed the "pain cave" in her mind. Courtney also shares how her training schedule is completely dependent on what her body and brain are telling her. Plus, we learn what it actually feels like crossing the finish line of a 100-mile race, and perhaps most importantly, what Courtney's donut of choice is.
