The Trailhead

Oladimeji Ajegbile, known online as Hello Dim, went viral for filming bike rides through Edinburgh with his two-year-old son perched on the handlebars, narrating every tree and bus he sees. He's also a former architect, UX designer, startup founder, stay-at-home dad, and, as of last year, a runner who clocked a sub-50 10K on roughly two training runs and just finished his first half marathon with a 50K trail ultra on the calendar. Zoë and Brendan talk with Dim about why the toddler videos connected when a decade of content didn't, the 90-day rule he uses to test every new pursuit, what the Piston Cup in Cars taught him about chasing medals, learning to ride a bike at 21, running the Union Canal in the pitch-black Scottish dark, getting dizzy at 30K of a track ultra, and his Substack essay on why achievement won't fix your emptiness. It's a conversation about being a beginner on purpose, making things for the process instead of the result, and what happens when the internet decides which part of your life it wants to see.

Singer-songwriter Margaret Glaspy joins Zoë and Brendan to talk about the strange and surprisingly rich overlap between running and making art. She shares how watching her mom run planted the seed early, growing up close to the Western States course, how Courtney Dauwalter and Addie Bracy helped draw her into ultrarunning, and why learning to sit with discomfort has changed far more than her athletic life. Margaret also talks about quitting social media, writing songs on a typewriter, finding solitude in anonymous hotel gyms, and the logistical challenge of training while touring in a van. Plus: the financial risks of falling on your guitar-playing hand, the unexpectedly deep musician-to-ultrarunner pipeline, and what Margaret might learn from how ICU nurses train for ultras.

Sam Robinson writes the Substack Footnotes , works as a content designer at YouTube, and has a PhD in seventeenth-century science, religion, and philosophy, which makes him exactly the right person to ask why we're all trying so hard to optimize a sport whose whole appeal is that it's beautifully pointless. Zoë and Brendan get into the tension with him: distance running rewards incremental gains and deferred gratification, and it's also the least efficient way imaginable to get from point A back to point A. Sam talks about racing above Stinson Beach with his head down, missing the view; about eating a protein bar in the shower at 4:58 a.m. to make a 7:30 meeting; and about how a three-year-old and a torn meniscus have both forced a slower relationship with the sport. The back half turns to Sam's piece on the fragility of type two fun and the male friendship crisis, what happens to shoulder-to-shoulder friendships when the run club scatters and the knee gives out, and whether shared mileage alone can hold a community together. Along the way: Robert Caro, Oliver Burkeman, Benjamin Franklin prosecuting his breakfast, and the unsettling possibility that morning-routine influencers have never actually seen American Psycho .

Heather Hansman is an award-winning outdoor journalist, an Outside columnist, and the author of Downriver and the bestselling Powder Days. Her new book, Fierce Country: The Untold Story of Three Women Who Ignited America's Love for the Wild, is out now. In this conversation: the therapist who mapped the heroine's journey, and the very famous mythologist who told her women don't need one; Georgie White swimming Grand Canyon rapids in 1945 in tennis shoes and a couple of hard candies; why there always seems to be exactly one available spot at the top for a woman, and what that has to do with the way we talked about Rachel Entrekin winning Cocodona outright; topophilia, or what happens when the love of your life turns out to be a landscape; and whether the American myth of the lone tough guy summiting the mountain is, frankly, a pretty boring story.

Formerly the Corner Canyon Ultra, now with a new name and a new course. The 11 Mile Classic climbs over 4,000 feet in five miles, the 20 Mile Challenge runs that loop twice, and there's a 5K if you'd like to keep your quads.

Adharanand Finn is an award-winning journalist and the author of Running with the Kenyans, The Way of the Runner, and The Rise of the Ultra Runners, and his forthcoming book The Running Pilgrim chronicles the 1,400 miles he ran around Ireland in 68 days. In this conversation, Zoe and Brendan talk with Adharanand about what Kenyan, Japanese, and ultrarunning cultures taught him about community and staying in the moment, why a pilgrimage is basically an ultra with better theology, the science of why running with other people feels easier, ultrarunning's weird romance with suffering, and the definitive (and expanding) playlist of songs about running. This episode is brought to you by Running Warehouse, where you can find everything you need to survive summer running, from vests to socks to a frankly irresponsible number of gels. Shop through the link in our show notes. Featured race: The Oregon Outback 230 is a 230-mile point-to-point journey from the eastern Cascades to Lakeview, Oregon, through the largest dark sky sanctuary in the world, happening July 16 through 21, 2027, with a 120-hour cutoff.

Anastasia Wilde is a Missoula-based adventure photographer who has spent the last five years shooting the country's biggest 200-mile races like Bigfoot, Tahoe, Cocodona, and hiking up to eight miles into the backcountry with thirty pounds of gear to photograph runners at their most unfiltered. In this conversation, Anastasia tells us how a Costco camera kit and a suspiciously well-timed $500 raffle win turned a middle school music teacher into one of ultrarunning's most prolific race photographers, why the mid- and back-of-pack will tell a stranger with a camera things they haven't told their families, the memory card catastrophe at the Bigfoot finish line she still thinks about, whether AI will ever make any of us look good while running (no), and what it means to photograph someone crying alone at sunrise on their way to a five-year buckle.

This week's featured race is the Machete Muertos 200 at Lake Perris, California, starting Wednesday, October 28. 200 miles, 44,000 feet of climbing, and a 96-hour cutoff at one of the toughest 200-milers in the country, part of Machete Madness's Día de los Muertos celebration.

Dillon Osleger is a geologist, professional mountain biker, and longtime trail steward whose debut book, Trail Work: Restoring the Paths and Stories of America's Public Lands, uncovers the buried history beneath the trails we run, ride, and take for granted. In this conversation, Zoe and Brendan get into why nobody wants to do the unglamorous work of maintenance (and the Kurt Vonnegut line that nails it) and how to read a trail like a layered history book. Dillon decodes what is hiding in plain sight, from barbed wire patents that date a fence to within two years, to the segregated CCC camps you can spot in the stonework, to the Indigenous place names that outlast every map. Along the way: what is quietly erasing two-thirds of America's historic trails, an extremely unhinged riff on trailmaxing as the next men's wellness trend, and a genuinely useful answer to the question most of us are too sheepish to ask, which is how do you actually start doing trail work.

Dr. Nick Tiller is an exercise scientist at the Lundquist Institute at Harbor-UCLA, a two-decade ultrarunner, and the author of The Skeptic's Guide to Sports Science and the new The Health and Wellness Lie . In this conversation: why ultrarunning is, by Nick's cheerful admission, not actually good for you, and why we keep signing up anyway; the red flags that should trip your bullshit detector in 2026; the great protein panic and how a "health halo" turns a Pop-Tart into a recovery food; what the evidence does and very much doesn't say about AG1; KT tape, cupping, and the slippery ethics of selling someone a placebo; and how to stay skeptical without curdling into a cynic whose brain has fallen out.

Featured race: the Ode to Laz Michigan Backyard Ultra, a 4.167-mile loop run every hour on the hour through 8,000 acres of Holly State Recreation Area in Holly, Michigan, on Saturday, July 18. The only way to win is to be the last runner standing, which is why the motto is "finishing last means the most." If you're backyard-curious but not ready to sign over your soul, the Oak Flats 3-hour option lets you dip in for one, two, or three loops. It's a championship-affiliated race, so the winner takes a silver ticket toward the USA national backyard team. Registration closes Thursday, July 16. Sign up at UltraSignup.com.

Ben Ratliff is a former New York Times music critic, a writing professor at NYU, and the author of Run the Song: Writing About Running About Listening, longlisted for the National Book Award and named a finalist for the PEN/Diamonstein-Spielvogel Award for the Art of the Essay, which chronicles what he hears when he brings music into his near-daily runs through the Bronx. In this conversation, Zoë and Brendan talk with Ratliff about why running made him a better listener, and why the optimal-BPM running playlist is, by his lights, beside the point. He makes the case for listening as active attention rather than ambient wallpaper, explains why some of the slowest and quietest music turns out to be the most enlivening to run to, and pushes back on the idea that "good taste" is something you can buy. Along the way: defamiliarizing a song until it sounds brand new, the strange kinship between a long run and a long DJ set, and how a career critic ends up running to everything from jazz to Ice Spice. This episode is brought to you by Running Warehouse, where Zoë gets basically all her summer running gear, vests, socks, hats, shirts, and a frankly irresponsible number of gels, with fast shipping and a return policy run by actual humans. This week's featured race is the FCA Endurance Race in Oakwood, Georgia — a choose-your-own-adventure event on a flat, one-mile paved loop around the University of North Georgia's Oakwood campus. Pick your distance: a 5K, a 10K that detours onto dirt and a stretch of cross-country trail, or a timed race of two, four, six, twelve, or twenty-four hours, with some durations offering a 6 p.m. start so you can run straight into the night. It all happens Saturday, June 6, 2026, and registration stays open right through race day. Sign up at UltraSignup.com. The Trailhead is part of the UltraSignup Podcast Network.

When you hit the wall at mile 19 of a marathon (or mile 80 of a 100-miler) it feels like your body is the problem. Your legs are concrete, your stomach is in revolt, and the finish line might as well be on the moon. But what if the wall is mostly in your head? Emily Balcetis is a social psychologist who studies how vision and perception shape motivation: how what people literally see changes what they believe they can do. She runs the SPAM Lab at NYU and is the author of Clearer, Closer, Better: How Successful People See the World. Her TED Talk on why some people find exercise harder than others has been viewed over a million times. Zoe and Brendan get into why highly motivated runners literally see the finish line as closer than it is, how Joan Benoit Samuelson used a woman in pink shorts to win the first Olympic women's marathon in 1984, and why the wall is a psychological phenomenon rather than a physiological one. Emily explains why willpower isn't a fixed trait you either have or don't, the if-then framework she calls foreshadowing failure, and how negativity bias means our brains lie to us about our own progress, which is why becoming your own accountant might be more useful than another motivational Post-it on the bathroom mirror. Plus: how Emily decided to learn the drums in a one-bedroom Manhattan apartment, and what it taught her about tracking the kind of progress the brain can't see.

David Raichlen is a professor of biological sciences at the University of Southern California whose research examines how human evolution, physical activity, and brain health are linked across the lifespan. In this conversation, Zoë and Brendan talk with David about what's actually happening in your brain when you go from couch to consistently active, why exercise might be the closest thing we have to a dementia preventative, and why his research on the runner's high, which famously involved humans, dogs, and ferrets, suggests it evolved as something more useful than feeling good. They also get into what hunter-gatherers like the Hadza can (and can't) tell us about how to live, why "more is better" hits diminishing returns at the high end, the trouble with paleo prescriptions, and whether sitting really is the new smoking. Plus: Brendan tries to figure out if his rock-climbing mom or his golfing dad is doing better cognitive work than he is.

Rochelle Bilow is a romance novelist, food writer, French Culinary Institute graduate, former Bon Appétit editor, and current kitchen gear expert at Serious Eats, and she just came back to ultrarunning after nearly a decade away from the sport. In this conversation, Zoë and Brendan talk with Rochelle about what she learned cooking on a farm that culinary school never taught her, why she pivoted from heartbreak memoir to romance fiction, and what it's like to balance writing deadlines with ultra training (her answer: ask for a deadline extension). They dig into why romance as a genre gets unfairly dismissed, what makes a great enemies-to-lovers arc, and the trail running romance novel she's currently writing. Plus: the $400 toaster that changed Rochelle's life, the truth about toaster oven air fryers, and the only correct way to clean a cloudy Vitamix. This episode is brought to you by LMNT.

Ryan Goodman grew up on a cattle ranch in Arkansas, studied beef cattle science at Oklahoma State University, and now manages WSU's beef cattle research program as Beef Cattle Operations Manager in Pullman, Washington, where he also teaches hands-on lab courses to the next generation of pre-veterinary students. Online, he goes by @BeefRunner. He also runs a lot of 100-mile races. In this conversation, Zoë and Brendan talk with Ryan about what six weeks of calving season: sleepless, high-stakes, completely indifferent to your training plan, taught him about finishing a hundred-miler, and why "one thing at a time" works as well in the Crazy Mountains of Montana as it does on a ranch at 2 a.m. They get into the complicated but more negotiable than you'd think relationship between ranchers and trail runners, the farm-versus-ranch distinction (I-35 is the line, roughly), why the heifers following you on BLM trail are curious not threatening, and Red Dirt music as the ultrarunning soundtrack you didn't know you needed. Also: cow tipping, the correct post-ultra meal, and whether Pullman counts as a town. This week's featured race is Mujeres and Marigolds, a women's only event with a 5k, 10k, 25k, 50k, and 100k relay! Thanks to TrailCon for supporting the podcast. Register now to attend!

C. Thi Nguyen is a philosopher at the University of Utah, a former food writer for the Los Angeles Times , a rock climber, and one of the world's leading thinkers on the philosophy of games. His new book, The Score: How to Stop Playing Somebody Else's Game , argues that games are the defining art form of our era, and that the scoring systems that make them so joyful turn quietly destructive when institutions and apps wield them instead. In this conversation, Zoë and Brendan talk with CT about why ultrarunning is a game in the deepest philosophical sense, his concept of value capture and why it explains your relationship with Strava better than you'd like, what carbon plates and trekking poles reveal about game design, and why Bernard Suits, the philosopher who defined play as "voluntarily taking on unnecessary obstacles", thought games might literally be the meaning of life. Also: fly fishing pickup artists, the shot clock, elite yo-yoing, and Zoë's Smash Mouth Strava segment situation.

Pavel Cenkl is a climate writer, ultrarunner, and Dean of Academics at Prescott College who has run hundreds of miles across Iceland, Scandinavia, and the Arctic through his project Climate Run. He grew up in the White Mountains, worked the AMC huts, started one of the first collegiate trail running teams in the U.S., and built a master's program combining movement, environmental philosophy, and ecology. In this conversation, Zoë and Brendan talk with Pavel about what happens when you push yourself to the edge of exhaustion in landscapes that are literally shifting beneath your feet — disappearing glaciers, the vulnerability of being utterly alone in midnight sun, why "resilience over resistance" is a better framework for running and life, and the moment he screamed so loud on day three of his Iceland crossing that he scared a goose into flight and accidentally had a paradigm shift.

Christie Aschwanden is a New York Times bestselling author, former lead science writer at FiveThirtyEight, and one of the sharpest science journalists working today. She's also a former elite Nordic skier for Team Rossignol and a national collegiate cycling champion, so when she set out to investigate the multibillion-dollar recovery industry for her book Good to Go, she brought both a scientist's rigor and an athlete's bullshit detector. In this episode, Zoë and Brendan talk to Christie about why cold plunges might actually delay your recovery, how your sleep tracker could be making your sleep worse, and why the most effective recovery strategies are boring, cheap, and unsexy. They dig into the rise of the "recovery industrial complex", from Tom Brady's infrared pajamas to cryotherapy chambers that NBA teams bought just because other teams had one, and what the research actually says about inflammation, ibuprofen, HRV, and the post-workout "window" myth. Christie also makes a compelling case for radical acceptance, situational awareness for your body, and trusting your own perceptions over your Garmin readiness score. Plus: the beer mile, knitting as recovery, and why pizza might be the most underrated performance fuel.

Brad Stulberg co-wrote Peak Performance with Steve Magness and has spent over a decade studying what excellence actually requires. He joins Zoë and Brendan to dismantle the myths of hustle culture and explain why genuine excellence isn't about optimization, it's about caring deeply about something worthwhile. We dig into "zombie burnout" (exhaustion from doing too little of what lights you up), what Brad learned from studying Courtney Dauwalter and powerlifter Layne Norton, and why chasing flow states prevents you from experiencing them. A grounded, research-backed conversation about pursuing excellence without losing yourself. Brad Stulberg is the author of The Way of Excellence , Master of Change , and The Practice of Groundedness .

What happens when you strip away sleep, ego, and every external measure of success for 330 kilometers? Doug Mayer, founder of Run the Alps, former Car Talk producer, and three-time Tour de Géants finisher, has spent years trying to answer that question. His new graphic novel, Last of the Giants , is his best attempt yet. In this episode, Doug joins Zoë and Brendan to talk about leaving a 25-year career in radio to build a trail running tour company in Chamonix, why he kept going back to one of the world's most grueling ultramarathons, and how he translated the experience of hallucinating in a snowstorm at 3am into a visual story. He shares what he learned from interviewing neuroscientists, a Buddhist monk who specializes in suffering, and the world's leading expert on pilgrimages, all in service of understanding why we do hard things and what we bring back from them. The conversation touches on "meeting the dragon" (a Buddhist concept for the moment when your usual tools stop working), the hero's journey, why Tour de Géants feels like "the PhD of ultrarunning," and how Doug accidentally started dating someone mid-race because her prefrontal cortex was too exhausted to know better.

Pat Cade has a PhD in mathematics, coaches high school cross country in Leadville, Colorado, and has finished the Leadville 100 six times. In this conversation, he explains what years of research math taught him about endurance: small steady progress compounds, inspiration only strikes if you're showing up every day, and sometimes the breakthrough comes when you stop following the plan and just go climb the mountain because it's beautiful outside. Pat shares how he and his wife landed in Leadville after leaving academia in New York, and how they decided to pour their energy into coaching and teaching after facing infertility. He breaks down what actually makes a good coach (hint: it's not yelling), why training at 10,000 feet requires rethinking everything you learned about recovery, and what the Leadville 100's Dream Chaser program is all about. He also attempts to explain his dissertation, including whether the universe might be shaped like a donut, in terms anyone can follow. Zoë and Brendan are mostly able to keep up.

For the final episode of 2025, Zoë and Brendan share their own year-end reflections, summits, snacks, and slogs, including Zoë's experience hitchhiking to the start line of a 78-mile race in Italy, arriving 90 seconds before the gun went off to stand between Kilian Jornet and Jim Walmsley in a downpour that would last 15 hours. Then they pull their favorite moments from this year's interviews. You'll hear coach Mario Fraoli explain why the marathon is where racing ends and insanity begins. Steve Magness on why running might be the healthiest cult you can join. Alex Hutchinson on the effort paradox, why we value things because they're hard, not in spite of it. Sabrina Little on running as a laboratory for virtue. And Dan Lieberman, who co-authored the original "Born to Run" research, telling Zoë and Brendan to their faces that ultra running is absolutely, completely, and totally bizarre.
