EP 735: The Aging Athlete-Exercise Physiology

What does it mean to be a trail runner in your 20s, 30s, 40s, 50s—or even your 70s? How do years of pounding dirt, chasing summits, and chasing goals shape our bodies, minds, and identities? 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 second episode of the Aging Athlete Series, we speak with Dr. Scott Drum, an exercise physiologist and lifelong endurance athlete. We explore how training, VO₂ max, heart health, sleep, and social connection evolve as we age—and how understanding these changes can help runners continue performing and thriving for decades. Dr. Drum explains how we can maintain (and even improve) cardiovascular fitness into our 50s and beyond, and shares his personal experience with AFib as a cautionary but hopeful tale. The conversation blends science, personal insight, and practical strategies to help runners of all ages stay motivated, train smart, and run for life.

To really understand who we are as a running community—What drives us, what connects us, and why we keep pushing our limits, we have to look back. Long before ultras, Strava segments, or finish-line belt buckles, there was pedestrianism—a 19th-century spectacle where athletes raced for six days straight inside smoky arenas, cheered on by thousands. Our resident ultrarunning historian, Davy Crockett, is back to introduce us to one of the most unforgettable figures from that era.  Peter Napoleon Campana—better known as Old Sport.  Davy just published another book, Old Sport Campana: Ultrarunning;s Most Popular and Amusing 19th Century Runner in his historical series that brings  Campana’s story to life and helps us explore what it reveals about the roots of our sport—and why looking back just might help us better understand who we are today.
