- 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.

Read on Substack - 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.

Read on Substack - Ultra running rewards obsession, but Tara Dower seems wired for something beyond results. She wants to solve hard problems, chase the best competition, run faster, and keep finding out what she’s capable of.
Tara joins me to talk Western States, her planned Pacific Coast Trail attempt, why she hasn’t raced UTMB, learning from Karl Meltzer, and her evolution with Altra from the Lone Peak to the new Vanish Carbon 3. Underneath it all is a bigger question: as Tara becomes one of the defining athletes of modern ultra running, what parts of herself does she want to keep?
For ultra runners interested in the people shaping where the sport goes next.

Read on Substack - Trail running has exploded into a global business, and Karl Meltzer somehow ended up at the center of it. HOKA turned his Speedgoat nickname into one of trail running’s defining shoes, Red Bull paid him to chase the Appalachian Trail record, and UTMB eventually bought the race he created.
Karl came up when ultrarunning was tiny and has watched the money, brands, athletes, and races transform around him. Josh and Karl talk about the strange experience of becoming valuable to an industry that barely existed when he started, selling Speedgoat to UTMB, his relationship with HOKA, and what someone who has lived through the entire boom thinks about where trail running goes from here.

Read on Substack - Ultrarunning eventually becomes a mental problem. The body hurts, the race stops going to plan, and the question becomes what the best ultrarunners understand about continuing when quitting makes sense.
Harvey Lewis has spent 30 years figuring that out. In part two of our conversation in Ohio, we get into the mental strategies behind Backyard Ultra, why different races require different mindsets, the failures that changed how Harvey competes, and what decades of Badwater, journey runs, and 200-milers have taught him about going farther than he thought possible.
