Trail Runner Nation

Caffeine is one of the most researched performance aids in sport, but Dr. Neil Clarke says its biggest misconception is that it works the same way for everyone. The research strongly supports caffeine for endurance performance, yet the right dose, timing, and delivery method can vary dramatically from one runner to another. Clarke explains how caffeine can reduce perceived effort and pain, increase motivation, and potentially help athletes sustain performance longer. The conversation covers coffee versus pills, gels and gum, caffeine during ultras, sleep, withdrawal, and why cutting caffeine before a race may not provide the boost many runners expect. For trail and ultrarunners, the most useful takeaway is surprisingly simple: start with a low dose, test it in training, and look for the smallest amount that improves performance without creating side effects.

Ryan Lange thought nine years of ultrarunning had given him a pretty good idea of his limits, until mile 88 of the Summit 200 changed everything. When he learned he was leading the race, pain suddenly became less important, his mindset shifted, and he began pushing at a level he hadn’t known was there. Ryan breaks down the practical pieces that helped make that breakthrough possible, including gradually shifting his sleep schedule before race day, training his gut to handle huge amounts of fuel, strategically using caffeine, keeping aid stations efficient, and giving his pacers permission to push him hard. He also explains why his training has evolved from 80 to 100-mile weeks toward a more sustainable 40 to 60 miles most weeks, because he wants running to support his life rather than consume it. The conversation goes beyond racing into how years of failing, adapting, and slowly improving have shaped Ryan as an entrepreneur and taught him to value discipline over instant success. Ultimately, it’s a conversati

For much of her career, Ellie Greenwood measured herself against the best runners in the world, but her relationship with running has evolved toward something less measurable and, in some ways, more meaningful. She talks with Don and Scott about why racing can gradually shift from exciting to stressful, and why stepping away from competition doesn't mean stepping away from being a serious runner. The conversation explores how personal projects, peak bagging, FKTs, mileage or vertical challenges, and even running every street in your hometown can provide the same motivation that once came from a race on the calendar. Ellie also tackles an important question for aging athletes: what happens when working harder no longer produces the performances it once did, and can changing the goal help preserve our love of running? Along the way, they share adventure ideas ranging from Rim-to-Rim-to-Rim and running a favorite race course unofficially to travel running and some wonderfully ridiculous challenges involving iron

Matt Lambert has become one of the quiet legends of the Auburn trail community, not because of race results, but because of the joy, generosity, and gratitude he brings to every run. Although he's a seven-time Western States finisher, Matt rarely talks about racing. Instead, he shares how growing up on the Western States Trail taught him that running is about adventure, friendship, and discovering the "pharmacy in your head," where movement naturally brings peace, perspective, and emotional healing. The conversation explores how our relationship with the trail evolves over time, why Matt intentionally stepped away from racing before it stopped bringing him joy, and how balancing running with other activities has allowed him to stay healthy for decades. Along the way, Don, Scott, and Matt reflect on why trail running creates deeper friendships than almost any other activity and how time on the trail often provides clarity that's difficult to find anywhere else. It's an inspiring reminder that the gre

Hydration can make or break a long run, but there isn't a universal formula that works for everyone. Kramer Ammons shares how he tests everything from sweat rate and hydration timing to where runners carry their water, explaining why the most efficient solution isn't always the most obvious. The conversation explores handheld bottles, hydration belts, vests, bladders, and why convenience often matters just as much as laboratory efficiency. Don and Scott add decades of racing experience, emphasizing that successful runners solve problems early instead of waiting until dehydration, stomach issues, or fatigue force them to slow down. The discussion also covers pre-hydration, electrolytes, carb drinks, aid station strategy, and how listening to your body is often more valuable than blindly following generic hydration guidelines. The biggest takeaway is that great hydration isn't about copying someone else's plan. It's about experimenting until you discover what consistently works for you. Links: Kramer's "how

Krissy Moehl, Kathleen Egan, and Jenny Jurek, affectionately known as the Mullet Train, share the story behind their goal of completing 1,000 trail miles together, including the Arizona Trail, High Lonesome 100, and Crazy Mountain 100. What started as an annual fastpacking adventure evolved into something much bigger: an intentional way to preserve friendship, challenge themselves, and keep adventure central as they get older. They talk candidly about learning each other's rhythms, figuring out how far their particular “train” can realistically travel each day, and discovering that a successful adventure doesn't always mean sticking stubbornly to the original plan. The conversation also gets wonderfully practical, covering ultralight gear, water, food, trail magic, trail names, cowboy camping, and the different “superpowers” each woman brings to the group. One of the most interesting shifts comes from Krissy, who spent decades racing at the highest level but now finds herself wanting to stop, take her shoes o

Coaching advice almost always starts with, “It depends.” In this special Ask the Coaches episode, Don and Scott take away that safety net by forcing Ian Sharman, Hal Koerner, and Ellie Greenwood to make definitive choices on some of trail running’s biggest debates. Is it better to be undertrained or overtrained? Should you trust data or your instincts? Would you add mileage or strength training? Can motivation be taught? Along the way, the coaches reveal not only their philosophies, but also the surprising amount of agreement behind them. Beneath the conversation emerges a consistent message: sustainable training, learning to listen to your body, and developing good judgment matter far more than chasing perfect numbers. It’s entertaining, occasionally chaotic, and full of coaching wisdom every trail runner can apply.

Sophie Grant had reached a point where even the hardest ultramarathons no longer carried the uncertainty they once did, and after years of infertility and IVF, she realized she had also lost some of her joy in running and trust in her own body. The Via Alpina changed that, taking her roughly 2,000 kilometers across the Alps and forcing her to approach each day without knowing exactly what the next one would bring. She and photographer Zoe Salt talk about the physical and logistical realities of nearly a month on the trail, including relentless fueling, strength training, bad patches, storms, forest fires, and the value of an exceptional crew. Sophie shares practical lessons endurance athletes can use immediately, including her belief that “a bad moment does not make a bad day,” the importance of eating before assuming something has gone seriously wrong, and learning to distinguish between not wanting to continue and truly being unable to continue. The deeper story is about something bigger than an FKT: Sophie

We often think of ultrarunning as an individual pursuit, but Eric Strand’s Western States story proves that the strongest performances are rarely solo efforts. After cracking a rib, falling multiple times, and watching his sub-30-hour goal slip away, Eric reached mile 78 convinced he wouldn’t make it. His pacers refused to believe that story, helping him stop negotiating with himself, stay focused on the mile he was in, and keep moving forward one step at a time. Along the way, the conversation explores what separates a great pacer from an average one, how trust and preparation begin long before race day, and why different moments require different kinds of encouragement. This episode is a reminder that sometimes the greatest gift another runner can give you is believing in you until you’re able to believe in yourself again.

Most runners focus on pace, heart rate, and fueling, but heat may be the hidden factor that determines whether a great race turns into a survival march. In this conversation, CORE endurance performance lead Aline Barre explains how the body regulates temperature, why overheating steals blood away from your muscles and gut, and how even well-trained athletes can unravel when heat gets ahead of them. She shares simple, research-backed ways to become heat adapted using overdressed runs, saunas, hot baths, and smart scheduling, while also explaining why hydration, electrolytes, and cooling strategies matter just as much. The discussion also explores CORE’s non-invasive temperature sensor, how monitoring heat strain can help runners avoid crossing the point of no return, and why “cooler is faster” isn’t just a catchy phrase, it’s physiology. This episode offers practical tools that can make running in the heat feel far more manageable. EPISODE SPONSORS Tifosi Optics - CLARITY ON THE TRAIL: Post your Golden Nugget

What would you think if you arrived at a trailhead and saw runners strapping full-size ironing boards to their backs? That’s exactly how Don and Scott discovered Iron X, a 13-mile extreme ironing race through the trails of Auburn, California. Race creator Ben Mitchell and participant Brian Goldman explain the surprisingly real world of extreme ironing, the rules of carrying an ironing board through the wilderness, and the seven checkpoints where competitors must stop and iron their shirts in places ranging from the American River to an abandoned car. But beneath the absurdity is something that feels increasingly important in trail running: grassroots events built around community, creativity, and simply having a good time. The conversation also explores the challenges facing small race directors, the value of low-key “fat ass” events, and Brian’s work helping financially struggling runners participate in the sport. It’s a reminder that some of the best trail running experiences may have nothing to do with qua

Runners have more data, technology, nutrition products, and training advice than ever, so why does Dr. Phil Maffetonebelieve many of us are actually getting slower and less healthy? In this wide-ranging conversation, Phil challenges the resurgence of high-carbohydrate fueling, explains why building a strong aerobic system still matters, and shares how he used heart-rate training decades before it became mainstream. He breaks down the Maffetone Method, why runners should measure training by time rather than miles, and how slowing down today can ultimately help you run faster tomorrow. The conversation also explores the difference between collecting data and actually using it intelligently, along with Phil’s belief that diet and metabolic health can quietly undermine even the best training plan. And in classic Phil fashion, the discussion eventually wanders into music, creativity, awareness, and why becoming a better runner may require developing more of yourself than just your legs.

Trail running has grown from a small community of passionate runners into a global sport, bringing bigger races, better gear, international competition, and more opportunities than ever before. Gaël Dutigny shares a firsthand account of witnessing UTMB from its very first edition in 2003 and reflects on how its evolution mirrors the growth of trail running itself. The conversation explores both sides of that growth, from crowded lotteries and commercialization to innovations in equipment, race organization, and worldwide access to incredible events. Along the way, Gaël, Don, and Scott discuss what makes iconic races so special, why local races still matter, and how runners can stay connected to the welcoming culture that first drew so many to the trails. It's a thoughtful discussion about preserving the soul of trail running while embracing the sport's exciting future.

Caffeine is one of the most researched performance enhancers in endurance sports, yet most runners know surprisingly little about how to use it effectively. In this conversation, Stone Creek Coffee founders Eric Resch and Amy Balestrieri separate the science from the myths, discussing when caffeine actually helps performance, why timing matters more than quantity, and how too much can hurt your sleep and recovery. They also explore why that morning cup of coffee is about far more than caffeine, touching on the rituals, psychology, and community that make coffee such an important part of endurance culture. Along the way, you'll learn about caffeine tolerance, race-day strategies, common misconceptions like dehydration, and even what goes into producing a truly great cup of coffee. You'll come away with a better understanding of how to make caffeine work for you and a new appreciation for the cup of coffee that starts so many great adventures.

Marc Hopkins, author of Hard Things, set out to write a book about running the Bigfoot 200, but what emerged was something much deeper. In this conversation, he shares how endurance running became the lens through which he uncovered old stories about self-worth, fear, identity, and the belief that one more finish line would finally make him enough. Together, we explore why runners chase hard things, the difference between simply enduring life and living with purpose, and how the trail can expose what's really driving us. Marc also opens up about surviving a 99% heart blockage, learning when grit is a strength and when it's time to stop, and why vulnerability may be the toughest skill endurance athletes ever develop. If you've ever wondered why you run, or found yourself learning more about your life than your splits during a long run, this conversation will stay with you long after the episode ends.

Tim Tollefson returns to Trail Runner Nation for a wide-ranging conversation about what makes trail running special and what happens as the sport continues to grow. Using a "Wheel of Trail Running" format, the discussion lands on two big topics: cultivating the next generation of trail stewards and the ongoing professionalization of trail running. Tim shares how his work with Runners for Public Lands and Mammoth Trail Fest has changed the way he views trails, volunteerism, and the responsibility runners have to give back to the places they love. The conversation explores everything from carrying a small saw on training runs to the challenges and opportunities created by big sponsors, larger race organizations, and growing prize purses. Throughout the episode, Tim makes a compelling case that trail running's future depends on balancing growth with the community values that built the sport. It's an honest look at how runners can help preserve trail culture while welcoming more people into it. Episode Sponsors:

Creatine has long been boxed into the weight-room world, but this episode opens the door to a much bigger conversation for trail runners and endurance athletes. Creatine is something surprisingly simple, "right within the reach of a glass," that may help athletes become stronger, faster, healthier, and more resilient. We discuss with Dr. Dan Pardi, Chief Health Officer at Qualia Life Sciences, whether this familiar supplement can support not just performance, but long-term health and better daily function. For runners who usually think about carbs, hydration, shoes, and mileage first, creatine offers a different kind of performance question: what if strength, recovery, and durability start with something small and easy? It's a practical topic for athletes who want to keep moving well, aging well, and showing up stronger on the trail.
