What does it take to keep running strong from your teens into your 90s? Welcome to The Aging Athlete, a new Trail Runner Nation mini-series co-hosted by ultrarunning icon Krissy Moehl. Every 5 to 6 weeks, we'll dive into what it looks like to grow older in this sport we love—exploring how to train smarter, fuel better, recover more intentionally, and stay motivated through the decades.

In this fourth episode of The Aging Athlete series, we sit down with Selene Yeager, a leading voice in reshaping how we think about performance, aging, and the female athlete. In this episode, she shares her personal journey from elite triathlete and gravel cyclist to trail runner, navigating midlife hormonal shifts. As the host of Hit Play Not Pause and coauthor of ROAR and Next Level, Selene opens up about redefining success, adjusting training and nutrition, and managing the mental side of aging. She offers practical, empowering insights drawn from science, storytelling, and her own lived experience. We also talk about the changes she's noticed in her own training and mindset while preparing for an ultra. Whether you're in your 30s, 40s, 50s or beyond, Selene's message is clear: your best athletic years might still be ahead.
