In this episode of Trail Runner Nation, we reflect on the evolution of trail running and the Trail Runner Nation podcast over the past 14 years. We reflect on some clips from our very first episode, Podcast Numero Uno, published in November of 2011. We discuss the changes in trail running gear, the importance of community and knowledge sharing, and the technological advancements that have shaped the TRN podcasting journey. The conversation highlights the significance of creating a gathering place for runners and the role of the podcast in fostering a sense of belonging within the trail running community.

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’re joined by Dr. Kelly Casperson to explore how hormone health influences endurance, recovery, and overall well-being as we age. Dr. Casperson, a board-certified urologist and women’s health advocate, brings her expertise to topics often overlooked in athletic circles—like menopause, libido, and the misunderstood role of hormone therapy. We dive into the physiological shifts that both male and female athletes face and how understanding these changes can help extend performance and vitality on the trails. From the importance of early hormone support to the mental health implications of declining hormone levels, we'll talk about aging with strength and knowledge.

What if the key to becoming a stronger, more resilient runner isn’t about pushing harder, but moving smarter? In this episode, we’re joined by Samuel Stow, ultramarathoner and movement coach behind Pop Running. With a background in aerospace engineering, Sam blends biomechanics, breathwork, and mindfulness to help runners reconnect with their core, activate their glutes, and move with intention. We explore how awareness, not intensity, leads to pain-free and efficient movement, both on and off the trail. Sam shares practical tips for posture, breathing, and body alignment that can transform your running experience.
