| 6/16/26 | ![]() Hunter Leininger: From 7-Year-Old Adventure Racer to Pro FKT Athlete | 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. This episode is brought to you in part by VKTRY: high-mileage carbon-plated insoles built to last over 1,000 miles, with a 90-day money-back guarantee. Find them at vktry.com.

| 6/2/26 | ![]() ATRA Founder Nancy Hobbs on Whether Trail Running Belongs in the Olympics | 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.

| 5/19/26 | ![]() Adventure Racing Legend Danelle Ballengee on a 60-Foot Fall, Two Freezing Nights, and the Dog That Saved Her Life | 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.

| 12/2/25 | ![]() Camille Herron on Science, Superpowers, and Setting the Record Straight | Camille Herron is the only athlete to win all three IAU Ultra World Championship distances, the only person to win both Comrades and Spartathlon, and the holder of world records from 50 miles to six days. But beyond the numbers, Herron is a scientist with a master's degree in exercise and sports science, a recently diagnosed autistic and ADHD athlete, and someone who has navigated more than her share of controversy. In this wide-ranging conversation with Buzz Burrell, Herron opens up about everything: her unconventional training philosophy of short, frequent runs over grinding long miles; the metabolic testing that revealed her unusual fat oxidation capacity; how neurodivergence has been both a superpower and a challenge in her career; and why, at 43, she's feeling more free and energized than ever, even without sponsors. The conversation doesn't shy away from harder topics. Herron addresses the Wikipedia controversy that cost her the Lululemon partnership, framing it as retaliation for her role as a sports whistleblower who has made multiple reports to USATF and the IAU. She also reflects on watching her records fall to Tara Dower and Caitriona Jennings with genuine enthusiasm, celebrating what she sees as a new era for women in ultrarunning. Whether you're here for the training insights, the fueling science, or the candid discussion of navigating public scrutiny, this episode offers a rare, unfiltered look at one of the most accomplished and polarizing figures in ultrarunning history. FOR MORE CONTEXT: The Wikipedia controversy referenced in this episode was first reported by Canadian Running Magazine in September 2024 and led to coverage in Runner's World, Women's Health, and other outlets. Herron's husband Conor Holt released a statement taking responsibility for the Wikipedia edits. Herron maintains her own account of events on her website. | — | ||||||
| 11/18/25 | ![]() Molly Seidel on Pressure, Injury, and Why She's Moving to Trail and Ultra Running | Olympic marathon medalist Molly Seidel joins host Buzz Burrell for a candid conversation about pressure, injury, and her shift into trail and ultra running. Molly unpacks her decision to drop out of the New York City Marathon, the long rebuild after breaking her kneecap, and why the trails feel like the right competitive home for the next phase of her career. She talks openly about identity, the culture of pain in endurance sports, and the growing doping problem in road running, along with why she's aiming squarely at a Golden Ticket at Black Canyon. Honest, sharp, and unexpectedly funny, this episode offers a rare look at an elite athlete redefining her path. Thanks to Arc'teryx for supporting The Buzz! | — | ||||||
| 11/4/25 | ![]() Kilian Korth's Triple Crown of 200s | This week on The Buzz, Buzz Burrell sits down in Moab, fresh off the finish of the Moab 240, with newly crowned Triple Crown champion Kilian Korth. In a season that redefined what's possible in ultrarunning, Kilian swept the 200-mile series, Tahoe, Bigfoot, and Moab, setting a new cumulative record and proving that success is built on years of setbacks. He opens up about how pulmonary edema, DNFs, and near-collapse moments became the foundation for his breakout year, why he prioritizes rest and recovery over mileage, and how a six-minute dirt nap can reboot the brain mid-race. From efficient aid-station strategy to fueling exclusively on simple sugars for nearly 60 hours, Kilian breaks down the methodical mindset behind running 200s fast—and the humility it takes to get there. He and Buzz talk sleep deprivation, hallucinations, and the mental games required to stay focused through multiple nights on foot. Plus, Kilian reveals his plans for 2026: the Cocodona 250 and a shot at the Colorado Trail FKT. Whether you're dreaming of your first 100 or fascinated by the world of multi-day racing, this episode is a masterclass in resilience, efficiency, and the art of going long. | — | ||||||
| 10/21/25 | ![]() Kilian Jornet on States of Elevation and doing 72 Peaks in 31 Days | Kilian Jornet joins The Buzz to talk about his States of Elevation project—72 U.S. 14ers in 31 days, covering 400,000+ feet of vert, 600+ miles on foot, and 2,500 miles by bike. He shares what he learned about the American landscape, endurance, and the body's ability to adapt, plus reflections on public lands, culture, and why the U.S. mountains feel like home. Thanks Arc'teryx for supporting The Buzz! They cover: How Kilian planned and executed his 31-day odyssey The difference between the Alps and American wilderness His take on access, adaptation, and why adventure still matters Presented by UltraSignup. | — | ||||||
| 10/7/25 | ![]() Candice Burt on the Edge of Endurance: 200-Milers, Nolan's 14, and the Limits of Too Far | In this episode of The Buzz, Buzz Burrell sits down with ultrarunning icon and race director Candice Burt, the woman who put 200-mile races on the map. From founding the Triple Crown of 200s to tackling self-supported FKT attempts on Colorado's infamous Nolan's 14, Candice has redefined what "too far" really means. They talk about what it takes to stay awake and moving for days on end, the psychology of pushing beyond comfort, and why even the most seasoned athletes need to respect the line between adventure and danger. Candice opens up about her 200-day streak of running 50Ks, the creation of the Arizona Monster 300, and what she's learned from organizing and rescuing runners in some of the toughest races on Earth. Together, Buzz and Candice explore how sleep, fear, and risk shape performance, and why the most meaningful endurance challenges aren't just about suffering, but about self-reliance, courage, and curiosity.

| 9/23/25 | ![]() Kat Baker on How Runners Can Save Public Lands | Public lands are where we run, where our races unfold, and where many of us feel most at home. But what happens when those protections are rolled back? In this episode of The Buzz, Buzz Burrell talks with Kat Baker, Executive Director of Runners for Public Lands, about the fight to keep 58 million acres of Forest Service land under the Roadless Rule, why iconic races like Western States, Wasatch, and Hardrock depend on these protections, and how runners can step up as stewards. Kat shares how RPL is rallying race directors, mapping where courses overlap with roadless areas, and helping runners become partners for land managers under strain. We also explore what runners can learn from climbers and other outdoor groups who've earned their seat at the advocacy table. If you've ever laced up on a forest trail, this conversation is for you. Public lands aren't guaranteed, they're a gift we all share responsibility for. 🔗 Learn more and join RPL: runnersforpubliclands.org 📅 September 28 is National Public Lands Day - free admission to all U.S. National Parks.

| 9/9/25 | ![]() Brian Metzler on UTMB, Trade Shows, and Trail Running Hot Takes | At this year's UTMB, it wasn't just about who won, it was about what the event has become. In this episode of The Buzz, host Buzz Burrell talks with longtime running journalist Brian Metzler about the transformation of UTMB Week into the sport's most competitive race series, biggest trade show, and all-out cultural festival. From Jim Walmsley's sprint finish at OCC, to Courtney Dauwalter's gritty 10th-place finish at UTMB, to Ruth Croft's commanding win, Buzz and Brian break down the racing itself before zooming out to ask what all the brand activations, media attention, and 175 million livestream views mean for the future of trail running.

| 8/26/25 | ![]() Jeff Mogavero on Professionalism, Croissants, and the Soul of UTMB | Take our listener survey! What does it take to thrive at the top of ultrarunning today? In this episode of The Buzz, Buzz Burrell sits down with Jeff Mogavero, fresh off his blazing Western States debut and heading into UTMB, to talk about how training has evolved from "just running when it feels good" to heat chambers, high-carb fueling, and precision hydration. Jeff shares the story of running in 110°F rooms with his pacer "Peanut," experimenting with 150 grams of carbs per hour, and why European races feel like the Tour de France compared to the costumed chaos of U.S. aid stations. He also reflects on directing his grassroots race in Missoula, balancing community with professional ambitions, and why UTMB still "has his soul." From croissants in Chamonix to chainsaw-wielding fans at Sierre-Zinal, this is a wide-ranging conversation about what's changing, and what still grounds the sport we love.

| 8/12/25 | ![]() Running the Length of Africa (and Beyond) with Fritz Sitte | Take our listener survey! It only takes five minutes, and you help us make better podcasts. Adventure runner Fritz Sitte isn't chasing podiums, he's chasing experiences. In this episode of The Buzz, Fritz joins Buzz Burrell to share the story of his 6,400-mile, eight-month run from Cape Town to the northern tip of Africa, completed alongside his brother on a bicycle. They talk about the challenges of covering a continent without motorized support, the life lessons learned from protecting their relationship on the road, and why lowering your boundaries (and your pace) can lead to deeper cultural connections. Fritz also gives a preview of his next big project: running the length of Germany to set an FKT while raising money for refugee education, plus a possible attempt in the Atacama Desert. Along the way, they dig into the philosophy of "meaningful meaninglessness," the value of strength training for long efforts, and why you don't have to run 100K a day to make a journey run worthwhile. If you've ever dreamed about ditching the race bib for an open-ended adventure, this conversation might just convince you to take that first step.

This episode of The Buzz is a special one. Recorded at TrailCon in Palisades Tahoe—wedged between Broken Arrow and Western States, Buzz Burrell sits down with four powerhouse women shaping the future of trail and ultrarunning. These aren't just elite athletes and insiders; they're advocates, leaders, and storytellers working to redefine what inclusion, equity, and longevity look like in the sport. Buzz chats with: Anna Frost, a pioneer of professional trail running, who reflects on the early days of sponsorship (free shoes!), standing up for equal prize money, and what it means to have longevity in the sport after motherhood.
