The Trailhead

Nick Thompson has spent his life chasing big stories and finish lines. The CEO of The Atlantic and author of The Running Ground joins Zoë and Brendan to talk about running through life's hardest moments, from a cancer diagnosis at 30 to balancing elite training with parenthood and a high-powered media career.  Together, they explore why running became Nick's anchor through chaos and change, the strange parallels between journalism and endurance sports, and the lessons he learned from his father, and why he runs to not become him. They talk about what aging athletes get wrong about decline, the emotional threshold of a "real" ultra (and the world's shortest one), and how Nick manages to fit sub-three-hour marathons into a 60-hour work week. Along the way, Zoë and Brendan share their own thoughts on parenting as endurance training, finish-line family moments, and why run commuting deserves a comeback.  The Running Ground: A Father, a Son, and the Simplest of Sports is out now from Penguin Random House.

What kind of person dreams up the hardest race on earth, and then follows it up with one of the weirdest? This week on The Trailhead, Zoë and Brendan dive deep into the mind of Lazarus Lake, the man behind both the Barkley Marathons and Big's Backyard Ultra. Our guest, author Jared Beasley, joins to talk about his new book on Laz, unpacking the mystery, mischief, and mythology that made one man's backyard into a global endurance phenomenon. We explore what drives people to suffer on purpose, why Laz's races capture our collective imagination, and what they say about the culture of ultrarunning itself. 🏃‍♀️ Featured Race: Yankee Springs Winter Challenge — 50K, 25K, 10K, and 5K distances in Middleville, Michigan on January 3, 2026.

Harvard evolutionary biologist Dan Lieberman is the scientist whose work reshaped how we understand running. His research on human evolution helped popularize the idea that we're born to run, that our bodies, from our toes and tendons to our oversized glutes, are uniquely adapted for endurance. In this conversation, he joins Zoë and Brendan to explore what running reveals about being human. This week's featured race is the Naughty Hog 100k, 50k, 25k, 10k, and 5k! Dec 20. Register now! We dig into why ultrarunning is evolutionarily bizarre but still deeply natural, what persistence hunting really looked like, and how belly fat, treadmills-as-torture-devices, and even the barefoot craze all tie into our running story. It's part science lesson, part reminder that while we didn't evolve for nipple tape,  running is still one of the most human things we do. Thanks to LMNT for supporting The Trailhead!

Joe Grant has always blurred the lines between athlete and artist. From racing UTMB and Hardrock to biking between Colorado 14ers, Joe's career has evolved into something bigger than competition—projects that fuse endurance, place, and creativity. In this conversation, Joe joins hosts Zoë Rom and Brendan Leonard to talk about his journey from racing to FKTs to local San Juan projects, why he ditched the watch, and how he balances gear geekery with poetry and film photography. If you've ever wondered how running can fuel creative work—or vice versa—this episode goes deep into what it means to truly be present on the trail.

This week on The Trailhead, Zoë Rom and Brendan Leonard sit down with one of ultrarunning's most quietly legendary figures: Junko Kazukawa. A two-time Leadwoman, breast cancer survivor, and one of the few athletes to complete both the Grand Slam of Ultrarunning and the Leadwoman series in a single year, Junko's story is a masterclass in resilience and joy. Born in Sapporo, Japan, and now based in Denver, Junko shares how she started running in the U.S. after coming over as a student, how she trained through cancer treatments, and why she still lines up for 100- and 200-mile races at age 62. She talks about the identity and community she's built through the sport, how her view of fitness has evolved over decades, and why she believes "glutes are everything." We also hear about her favorite races around the world, from the Tour de Géants to Mount Fuji, and what keeps her motivated to take on new challenges even as recovery gets harder with age. Whether you're chasing your first ultra or your 26th, Junko's joy and perspective will make you want to lace up and keep going. Thanks to Running Warehouse for supporting The Trailhead.

Sarah Lavender Smith, a writer and passionate trail storyteller, shares her journey from journalism to the vibrant world of trail and ultrarunning. She discusses the transformative power of running during midlife and candidly explores her evolving relationship with alcohol. With laughter and reflective insights, Sarah recounts her experience finishing the Hardrock race at 56 and emphasizes the importance of acceptance in endurance. The conversation delves into family dynamics at races and her exciting project: a memoir capturing the essence of resilience through the trails.

Nick Triolo, a writer and ultrarunner known for his book The Way Around: A Field Guide to Going Nowhere, delves into the freedom of running without metrics. He discusses the joy of loop running, embracing presence over performance, and how circling back can be more fulfilling than chasing summits. The conversation highlights the transformative nature of running as a creative practice, the tension between ambition and societal expectations, and the beauty found in nature during personal journeys. A light-hearted debate about favorite running loops adds a fun twist!

In this episode, Zoë and Brendan sit down with Tommie Runz (@tommie_runz): plant-based athlete, podcast host, father, and (accidentally?) ultra-endurance legend. Tommie didn't grow up running, but after choosing sobriety in 2017, he found clarity, purpose, and eventually, a new identity in the miles. We trace his journey from gym rat to six-star marathon finisher to taking on The Speed Project solo—six ultramarathons in six days across the desert, with no prior experience beyond 26.2. He opens up about recovery (physical and emotional), the myth of "rock bottom," and how a surprise video from his kids mid-race broke him down, and gave him the strength to keep going. Also: vegan aid station food, the case for trekking poles on pavement, and whether road ultras are actually super hardcore.  Thanks to our partners at LMNT – A tasty electrolyte drink mix with everything you need and nothing you don't.
