"Doubt and belief can coexist. In the book, you see a ton of my doubts and struggles with confidence. But then there's also this untouchable belief that's always there, too. So it's almost like, which voice are you going to listen to?" It's a big week for professional runner Sara Hall! She turns 43 tomorrow, and then heads east to race the Boston Marathon on Monday. And while most marathoners are recovering on Tuesday, Sara, in true Sara form, will be doing the opposite: It's book launch day! Sara's debut memoir, For the Love of the Grind, comes out April 21, and in this conversation, Sara talks about why the time was right to write a book. She talks about what the writing process was like, about the part of the book that's likely to shock readers, and about why she wanted to get in touch with Eminem before the book came out. Plus, how she's feeling heading into Boston 2026. SPONSOR: Lagoon.
