“She said, ‘This is how it was supposed to be. This is how it was supposed to feel.’ And at that moment, I realized the magnitude of what we gave to each other.”

Rerun alert! In honor of the 129th Boston Marathon in just a few days, we're throwing it back to 2022, when fan favorite and beloved Peloton instructor Jess Sims surprised the world by showing up at the start (and finish!) line of the Boston Marathon. And she had a good reason for keeping her marathon debut on the down-low. In this very special conversation, Jess talks about receiving a fateful message from Boston Marathon bombing survivor Michele Blackburn — a message that ultimately guided Jess every step of the way toward that finish line on Boylston Street. Jess talks about her training, about how she felt on the start line, and about why she still feels marathon imposter syndrome, even after earning that blue and yellow medal. (You’ll want tissues on hand 17 minutes into this one. You’ve been warned.)

Stuff You Should Know
Boysober

Boysober

Have you ever wondered what life might be like if you stopped worrying about being wanted, and focused on understanding what you actually want? That was the question Hope Woodard asked herself after a string of situationships inspired her to take a break from sex and dating. She went "boysober," a personal concept that sparked a global movement among women looking to prioritize themselves over men. Now, Hope is looking to expand the ways we explore our relationship to relationships. Taking a bold, unfiltered look into modern love, romance, and self-discovery, Boysober will dive into messy stories about dating, sex, love, friendship, and breaking generational patterns—all with humor, vulnerability, and a fresh perspective.
