The Trailhead

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.
Thanks for spending 2025 with The Trailhead. See you on the trails in 2026.
Featuring: Mario Fraoli, Steve Magness, Alex Hutchinson, Sabrina Little, and Dan Lieberman

Romy Ancona is a DJ, trail runner, and the force behind Broken Arrow's famously joyful finish line. Born in Cozumel and now based in Colorado's Roaring Fork Valley, Romy learned to mix on a trackpad on their mom's Windows laptop before somehow landing their first gig at a Maxim Magazine party in Hollywood. These days, they split time between spinning tracks on the mountain and chasing vertical on skis and trails.
In this conversation, Romy talks about shedding DJ ego, their work on Broken Arrow's inclusivity advisory council (think glitter, bubbles, and rainbow slip-and-slide dreams), and how a 2022 accident that broke their back reshaped their relationship to running. As they put it: as much as moving hurts, not moving hurts more. Plus: the lost art of the mixtape, why they watch pro paintball on the treadmill, and a running playlist spanning Celia Cruz to Limp Bizkit.

Lindsey Freeman is a sociologist, writer, and lifelong runner whose book Running offers a feminist and queer reading of the sport. In this conversation, Zoë and Brendan talk with Lindsey about what it means to treat running as a practice, becoming yourself through repetition, staying soft, and trusting that showing up matters even when outcomes don't.
The conversation moves through ideas like the magic circle that makes it acceptable to try really hard in public, the growth of queer run clubs, and the strange emotional math of caring deeply about things that often disappoint you. There's also a delightful tangent about Stuart Murdoch of Belle and Sebastian being a serious runner. Lindsey's advice for writer's block and bonking alike? Have a snack and come back tomorrow.
