    Anton Krupicka | Trail Running, Identity, and Ignoring Trends

    22/09/2026 | 24 mins.
    Anton Krupicka has spent two decades becoming something harder to define than a trail runner. This conversation is about how that happened, why he stopped caring about fitting the sport’s mold, and what it looks like to keep evolving without chasing relevance.
    We talk about the injury that changed his relationship with running, the move toward scrambling and climbing, his influence on trail culture, the Leadville comeback, and why La Sportiva still makes sense for the athlete he is now. More than anything, it’s Anton on identity, aging, design, and trying to stay the peak version of yourself without pretending you’re still who you were ten years ago.

    The Trail Races We Can’t Afford to Lose

    15/09/2026 | 28 mins.
    Trail running is growing fast, but what happens to the races that don’t scale cleanly? After spending one night volunteering at the Wasatch 100 and the next day at a brand-new UTMB race, I came away wondering whether the messy, human parts of ultra running are exactly the parts we can’t afford to lose.
    Pacers, old-timers, exhausted volunteers, DNFs, polished finish lines, UTMB, and the strange ways a race becomes more than a race. This isn’t an argument for grassroots over corporate. It’s about why trail running needs both, what each is uniquely good at, and what disappears when every race starts looking the same.

    "I Need Running to Stay Alive" | Inside the Compulsive Mind of Biel

    08/09/2026 | 29 mins.
    Ultrarunning rewards people who can keep going. Biel makes you wonder what happens when stopping no longer feels like an option, and where ambition ends and compulsion begins.
    Biel is a Brazilian ultrarunner, Speed Project athlete, tattoo artist and printmaker living in Berlin. He has represented Brazil at the 24-Hour World Championships and set records from Los Angeles to Las Vegas and Chamonix to Marseille. But the more interesting story is the force connecting his face tattoos, his art and the extreme experiences he says he needs to stay alive.

    UTMB Doesn’t Have a Fan Problem

    01/09/2026 | 35 mins.
    UTMB is the center of trail running for one week every year, and somehow the people most frustrated by it keep showing up. After a week in Chamonix, I came home thinking the problem with hating UTMB is that the race keeps complicating the argument against it.
    The fan experience is better than the criticism suggests, TDS might be the hardest race of the week, the women are racing with ego, and some of the most interesting parts of UTMB have almost nothing to do with racing. Ten observations from inside the chaos, including what brands keep getting wrong, what Chamonix reveals about status in trail running, and why everyone should be reading Raz Rauf.

    Why the World’s Biggest Trail Race Happened in France

    22/08/2026 | 39 mins.
    UTMB is the biggest trail race in the world, but why did it happen in France? The easy answer is Mont Blanc. The better answer has more to do with culture, timing, and the kind of endurance tradition that was already there long before UTMB existed.
    Josh talks with Doug Mayer, founder of Run the Alps and author of The Race That Changed Running, about the deeper conditions that made UTMB possible, from old mountain races and ski mountaineering to the Pellettis’ execution and the way places like Vallorcine turned the race into something people gather around, not just run.
