At seven years old, Hunter Leininger talked his way into his first adventure race; by ten he was a national champion, and he's spent the eighteen years since turning a childhood obsession into a profession, holding the fastest unsupported traverse of Iceland (370 miles), the FKT for the 1,110-mile length of Florida, and a Guinness World Record for climbing all fifty state high points. In this conversation, Buzz and Hunter get into the strange education of growing up sleep-deprived (including the time his dad towed him by bungee cord while he sleepwalked through a 2 a.m. trek), the actual tactics of staying awake for days (pre-loading caffeine before the crash, fueling so you never fall behind, the ninety-second dirt nap )and how adventure racing builds the kind of toughness that's quietly producing today's best ultrarunners. Then the industry question Buzz can't resist: how a 25-year-old with no Western States win built a full-time career out of FKTs, TV shows, and content, and what the freelance-athlete model means for everyone trying to make a living in a sport with no teams and almost no prize money.

Nancy Hobbs founded the American Trail Running Association in 1996, helped establish USATF's Mountain Ultra Trail Council and chaired it for decades, and has served on the international boards governing trail and mountain running for some thirty years. Buzz and Nancy get into the underbelly of the sport: the governance. They cover how the USATF Mountain Ultra Trail Council grew from a $750 annual budget to six figures, what a membership fee actually buys you (secondary medical insurance and drug testing, not just a warm fuzzies), why the biggest races, UTMB, Hardrock, Western States, aren't the official championships and what that imbalance does to the sport, the women reshaping who shows up on the start line, and the question Buzz keeps poking at: does trail running belong in the Olympics, and would it survive the trip? Also: a throwdown, a postcard, and a hard-won case for permission to walk. The Buzz is brought to you by Wahoo treadmills, and VKTRY insoles.  The Buzz is part of the UltraSignup Podcast Network.

Danelle Ballengee is one of the most decorated endurance athletes in American history, a four-time Pikes Peak Marathon champion, two-time Adventure Racing World Champion, and six-time US Athlete of the Year across four different endurance sports. In December 2006, on a routine training run near her home in Moab, she slipped on black ice on the Amasa Back trail, fell roughly 60 feet, shattered her sacrum, broke her pelvis, and spent two sub-freezing nights alone in the desert before her dog Taz led search and rescue to her location. In this conversation, Buzz sits down with Danelle at the Moab Public Library to revisit the golden era of adventure racing under Mark Burnett's Eco-Challenge, coming back two decades later for Bear Grylls' rebooted World's Toughest Race: Eco-Challenge Fiji alongside Travis and Mark Macy, the fall that should have killed her, and what it feels like to live what she calls borrowed time. Danelle is the founder and race director of the Moab Trail Marathon and Half Marathon, held the first weekend in November.  Check out VKTRY performance insoles that allow you to make any shoe a carbon shoe for a fraction of the cost.  The Buzz is part of the UltraSignup Podcast Network.  

Matt Carpenter is the most decorated mountain runner in American history, 18-time Pikes Peak champion across twelve marathons and six ascents, holder of the Pikes Peak Marathon course record at 3:16:39 since 1993, and the man who took 90 minutes off the Leadville Trail 100 record in 2005 with a 15:42:59 that stood until 2024 when broken by David Roche. In this conversation, Matt walks Buzz through what 33 years on top of Pikes Peak actually requires: the obsessive training math behind the 3-2-1 workout above 12,000 feet, the consistency-quality-quantity-rest pyramid that shaped every season, why a 90.2 VO2 max isn't the whole story (running economy is, and his was poor until he trained it), and the moment Ricardo Mejía's 1992 win lit the fire that produced the record the following August. They get into Matt's Fila SkyRunners years racing flat marathons at 17,060 feet in Tibet, his unconventional Leadville fueling system, 50 calories every ten minutes, watch set to beep, why he carried bottles in his armpits before running vests existed, and what made him retire on his own terms at 47 after winning Pikes Peak six years running. Plus the custard shop, the Planet Fitness bench-press streak, and a clear-eyed take on whether his marathon record will ever fall.

Dave Mackey is a two-time USATF Ultrarunner of the Year, former rim-to-rim-to-rim Grand Canyon record holder, JFK 50 champion, and, after a freak fall off Bear Peak in May 2015, thirteen surgeries, and a voluntary below-the-knee amputation in November 2016, one of the more improbable comebacks in the sport. Buzz and Dave recorded the first part of this episode on the exact rock Dave fell off, on the summit of Bear Peak, in an actual snowstorm, wearing actual shorts. In this conversation, Dave walks through the accident itself and the friends who got him off the mountain alive, why he ultimately chose amputation over more reconstruction, what proprioception feels like on a carbon-fiber running blade, his pre-Western States taper (rock climbing in Tuolumne Meadows), being one of the first American athletes to lace up a pair of absurd-looking early Hokas, and why he thinks modern ultrarunners are faster, better rested, and, for the most part, smiling more than his generation did. He's signed up for the Leadville Challenge again this summer, and he's still, as Travis Macy puts it, a runner's runner.

Jason Blevins is a veteran journalist at the Colorado Sun who has spent nearly three decades covering outdoor recreation, public lands, and the mountain communities of the Colorado high country. In this conversation, Buzz and Jason dig into the slow-motion crisis unfolding across the Rocky Mountain West, a snowpack at 61 percent of normal, a 103-year-old Colorado River Compact straining under the weight of 40 million people's water needs, and ski towns facing an identity reckoning that has been building for years. They talk about what it looks like when mountain communities diversify away from a sole reliance on chairlift riders, why the ideal town might be "just shitty enough," and how the housing crisis in places like Crested Butte and Aspen is a preview of pressures playing out across the country.  The conversation opens up into something larger: outdoor recreation as a $1.3 trillion industry that has earned a seat at the policy table — and the responsibility that comes with it.

Buzz sits down with Karl "Speedgoat" Meltzer, 50-time 100-mile winner, previous Appalachian Trail FKT holder, and the man behind one of trail running's most iconic nicknames , for a conversation about a career that has never followed the obvious path. Karl is currently at 93 hundred-mile finishes, closing in on a goal he set four years ago: 100 finishes by the summer of 2027, with Hardrock 100 as his dream finale. They dig into the origin of the Speedgoat nickname (a jackrabbit, Highway 70, a Fila shoe called the Escape Goat), what it looks like to hold a perpetuity royalty deal with Hoka on one of the best-selling trail shoes in the world, and what Karl learned across three AT record attempts about the difference between being an elite hundred-miler and being ready for multi-day. Plus longevity, old-school zone-five-or-nothing training, speed golf at Bandon Dunes with Bernard Lagat and Nick Willis, and the homemade bobsled runs that once left Buzz's sacrum bruised for four days. Karl is 58, still running for Hoka through 2027, still operating on the same principle that drove him through his Snowbird bartending years: live first, die later. The record will stand for a while. The shirt is coming. This episode is brought to you by Wahoo Kickr Run: run-free mode, automatic grade control from -3% to 15% incline, and the closest thing to outside without going outside.

Sean O'Rourke holds a PhD in computational physics. He also lives in a Ford Transit Connect, bathes in hot springs, and has climbed roughly 2,000 peaks across the American West, South America, the Alps, and Central Asia, mostly alone, entirely self-funded, and almost completely off the radar. He goes by Dr. Dirtbag, a name he's been writing under since 2010. This conversation is about what happens when someone with serious credentials looks at the conventional post-graduate path and quietly walks the other direction. Sean teaches computer science and coaches Nordic skiing remotely, which frees him to spend most of his time on what actually interests him: bike mountaineering in Kyrgyzstan, tagging remote six-thousanders in the Puna de Atacama, and attempting the 82 Alpine summits over 4,000 meters entirely self-propelled, a project that ended with a loose rock, a broken toe, and a 143-euro emergency room bill in Aosta.

Ski mountaineering just made its Olympic debut at the 2026 Milano Cortina Winter Games, the first new sport added to the Winter Olympics since 2002. Nikki LaRochelle, former U.S. Ski Mountaineering National Team member and color commentator for Olympic Broadcasting Services, joins the show live from Milan to break down everything that happened. The headline for trail and ultrarunners: mountain runners Cam Smith and Anna Gibson placed fourth in the mixed relay, finishing ahead of Italy, Austria, and Germany. Gibson picked up the sport less than a year ago and delivered a masterclass in pacing that stunned even seasoned observers. France took gold, Switzerland silver, and Spain bronze, capping a historic week for Oriol Cardona Coll, who won the first-ever Olympic gold in men's skimo, Spain's first Winter Olympic gold since 1972. Buzz and Nikki also discuss what Alysa Liu's joyful figure skating gold can teach endurance athletes about reframing pressure, how skimo landed with the broader public, and whether trail running could one day join the Games.

A World Mountain Running champion, a 100K road world champion, a Mount Marathon winner, a top finisher at Comrades and Sierre-Zinal, the range is almost absurd. But when Buzz sits down with Max, the thread running through all of it isn't ambition or optimization. It's fun. After burning out post-college and stepping away from the sport for two years, Max made a pact with himself: keep running only as long as it stays enjoyable.  Three decades later, that philosophy has carried him from obstacle courses to Welsh castles, from the track to the trails of southern China. In this conversation, Max and Buzz dig into what it actually looks like to maintain elite fitness across wildly different disciplines without specializing, how Max taught himself to climb like a European mountain runner after finishing 81st at his first Sierre-Zinal, and why the motivation to grind through big training blocks shifts as you age. Max talks honestly about what slowing down feels like at 46, the surprising role collagen and creatine have played in his recovery, and why he's now chasing bucket-list races like the Dipsea over podium finishes at marquee ultras. The two close with a reflection on the growth of trail running worldwide, from local hundred-person races with hand timing and burritos to 5,000-person events in China, and why Max believes the soul of the sport will survive the spectacle.
