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.

Over two years ago, we introduced the concept of Misogi—doing something so challenging it changes you—through Michael Easter’s book The Comfort Crisis - Discomfort to Reclaim Your Wild, Happy and Healthy Self. Now, we’re revisiting it with fresh eyes and deeper insights. In a world built for convenience, what does it truly mean to seek out discomfort? And how can that mindset shape us into stronger runners—and better people? Join coach, Adam Kimble, and us as we explore boredom, solitude, hunger, and the wild places that force us to grow.

Here is the link to Adventure Scientists that Adam talked about.

In this episode of Trail Runner Nation, cognitive neuroscientist and endurance athlete Dr. Scott Frey reveals how brain training can unlock new levels of performance for trail and ultrarunners. He explains that while most athletes focus on the physical, it’s often the brain that sets the limits—through perceived effort, cognitive fatigue, and pain signals. Dr. Frey introduces his Brain Endurance System Training (BEST), a method that combines cognitive and physical training to build mental strength and resilience. We talk about managing cognitive load, how the brain predicts fatigue, and why a mental taper can be just as important as a physical one. Listeners will learn how to train smarter, race longer, and enjoy the sport deeper by understanding the true power of the brain.

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.
