Barkley Marathons is famous for suffering, but Max King explains the part most people miss: it’s a puzzle that rewards cooperation as much as fitness. We talk about why he’s drawn to deep-woods, off-trail navigation, how the old-school “tear a page from a hidden book” checkpoints actually make sense, and what it takes to build the kind of year-to-year knowledge that can move you from survival to real progress. If you’ve ever wondered why even elite runners struggle there, Max makes it painfully clear.

We also get into a major career shift: after a long run with Salomon, Max joins Kylas Fuga and breaks down what he wanted from a sponsor at this stage of his career. We talk trail running shoes in the details that matter, including durability, outsole grip, and why he’s leaning into more cushioning as he gets older. He shares what he’s using now, what he still wants for more aggressive terrain, and how he hopes the brand will reach the American trail running market through better distribution and hands-on demos.

From there, we zoom out to longevity, recovery, and the realities of coming back from injury. Max walks through his meniscus tear, what helped him return, and why rebuilding true world-championship fitness can take longer than simply running again. We also tackle the growth of trail running, the pull between UTMB-style races and World Championships, and Max’s blunt take on anti-doping: when someone cheats, it doesn’t feel theoretical, it feels like stealing from friends.

She’s calling in from the backcountry of Utah with a Starlink connection, fresh off slot canyons, desert miles, and yet another FKT. Erin Tun is back, and our catch-up quickly turns into a deep look at what it actually takes to move fast in the mountains when the air is thin and the consequences are real.

We dig into Erin’s four-month South America push anchored by altitude training in Quito, Ecuador, where repeat climbs and local trail running community support helped set the table for bigger goals. From Cotopaxi and other 5,000 meter peaks to the main objective, Aconcagua, Erin breaks down the real-world mechanics of a fastest known time attempt: scouting versus full summits, choosing lines, managing snow and scree, and why a perfect weather window can disappear overnight. She also describes what performance feels like above 21,000 to 22,000 feet, where “going hard” often means relentless efficiency and not stopping, not running a pretty pace.

From there, the lens widens to the Seven Summits record path, including why Kilimanjaro might be next and what makes an Everest speed record uniquely complicated: oxygen choices, north versus south side routes, political access, permits, and the funding reality behind big peaks. We also talk sponsorship in a way most podcasts skip, including Erin’s move to Tava, her hands-on role testing prototypes, and how building a sustainable career as a modern mountain athlete now includes storytelling, not just results. If you want the behind-the-scenes version of these adventures, Erin and Chris are launching a YouTube channel to show what Instagram can’t.

She steps away from competition for years because of serious health issues then returns with a top-five at Transgrancanaria and an audacious Sierra project that looks more like an alpinist’s dream than a runner’s itinerary. Olivia Amber joins us from Bishop, California to talk about building a comeback that’s less about hype and more about durability, curiosity, and doing hard things for the right reasons.

We dig into how a Midwest childhood and an All-American Nordic skiing background shaped her engine, her grit, and her love for long days. From there, we get practical about life on the Bishop and Mammoth corridor: altitude training, endless vert, technical trails, the climbing community, and why that access changes what’s possible week to week. Olivia also breaks down big wall climbing, the mental side of exposure, and the “systems” skills that matter when mistakes have real consequences.

Then we go deep on Normans 13, the open-ended FKT linking 13 Sierra 14ers with huge climbing, talus, cross-country travel, and a brief 5.9 crux at 14,000 feet. Olivia explains her north-to-south strategy, how she planned logistics and resupplies, what sleep deprivation actually felt like over multiple days, and why the experience hit differently than racing. We also hear what it was like joining Kilian Jornet during his attempt and what she’s learning from The North Face team across running and climbing.
