Description

Borderlands Trail and Ultra Running is a storytelling podcast for ultra runners who love this sport deeply, the iconic races, the legendary athletes, the gear, and the culture that makes all of it worth caring about.

Hosted by Josh Rosenthal, founder of Borderlands Trail Running, this show exists to collect the ultra running stories that define the sport, from spending a day at Laz Lake's home to deep conversations with Scott Jurek, Dean Karnazes, Camille Herron, and the everyday runners doing extraordinary things out on the trails.

This podcast covers the full world of ultra and trail running: race coverage and analysis of marquee events including Western States Endurance Run and UTMB, honest trail running shoes reviews and ultra running gear breakdowns from someone who has tested 44 pairs over 6,000 miles, and big conversations about where the sport is headed, including what dirtbag runners bring to a sport that's growing fast.

This show gives ultra runners the stories, perspectives, and gear knowledge to go deeper into a sport they already love while celebrating what makes trail and ultra running unlike anything else.

We'll answer questions like:

- Who is Laz Lake, and why does everyone in ultra running revere him?
- What makes the Barkley Marathons the hardest race in the world?
- How does Western States Endurance Run work, and why is it so hard to get in?
- What are the best trail running shoes and ultra running gear right now?
- Who are the greatest ultra runners of all time?
- What does dirtbag running culture actually mean?
- How is ultra running changing, and is that a good thing?
- What does it take to run a 100 mile ultra marathon?
- What should ultra runners eat during training and on race day?

If you want the stories, the gear, and the culture that make ultra and trail running the most addictive sport on earth, you're in the right place.

Ultrarunning is evolving and growing fast and with that growth, ultra running feels different. Josh digs into how the sport is changing as it becomes more competitive, more visible, and more professional than ever before and asks whether something essential is being lost along the way. From duct-taped water bottles and campfire start lines to global races with thousands of runners and highly engineered gear, this episode explores what that shift really means. From the rise of new brands and technologies to the increasing professionalization of the sport, the conversation looks at what we’ve gained—and what we might be leaving behind. Not as something to judge, but as an evolution that is reshaping how ultrarunning feels, who it’s for, and where it’s going next. For runners thinking about how ultrarunning is changing and what that means for the future of trail running and ultrarunning.Please give us a follow, rate the podcast, and give a review.Topics / Timestamps00:00 The Evolution of Ultra Running02:23 Defining the Charm of Ultra Running07:15 Ultrarunning is Really Two Sports in One11:54 Professionalization vs. Community17:00 The Standardization and Predictability of Ultra Races23:43 The Trade-Offs of Growth - we're losing somethingResources / LinksLa Barba CoffeeACGGorge WaterfallsMountain OutpostWestern StatesLeadvilleWasatch 100Barkley MarathonsEcoTrail ParisRelated EpisodesDirtbag Culture vs. Luxury Running BrandsHow Ciele Athletics Built a Running MovementPresented by Kiprun.----Find us at Borderlands.cc and sign up for the newsletter.Want to run in the Salt Lake area?

If you've ever wondered why luxury running brands suddenly started appearing in ultrarunning—a sport built on dirtbag ethos, thrift-store gear, and anti-status culture—this episode explores the tension behind it.Josh unpacks where the idea of luxury collides with traditional ultrarunning culture, what actually defines a luxury running brand, and why some runners see it as evolution while others see it as a threat to the identity of the sport. At the center is a deeper question: is ultrarunning defined by what you wear, or simply by the act of running ultras?For trail and ultrarunners curious about how culture, identity, and authenticity are evolving in the sport.Please give us a follow, rate the podcast, and give a review.Time Stamps01:14 Why does Luxury Feel Strange in Ultrarunning?03:45 What is Traditional Ultrarunning Culture?10:48 5 Markers of Traditional Ultrarunning Culture15:44 What even is luxury?20:40 What is a "luxury running brand"?24:25 Why do luxury running brands bother people?27:43 A Weird Moment in Luxury Ultrarunning31:45 The Old Guard of UltrarunningResources / Links[article] Why “Luxury Running Brands” Feels Strange In UltrarunningSatisfyCurrentlyRunning SucksRelated EpisodesSatisfy Cofounder, Brice PartoucheThe ROCKER Shoe is Fear & Loathing in Las Vegas----Presented by Kiprun.----Find us at Borderlands.cc and sign up for the newsletter.Want to run in the Salt Lake area?

Trail running doesn’t have journlists and no one’s holding the sport accountable. I think memes might be the closest thing we’ve got and that’s just one of the 10 things on my mind this week..This week I pulled up a chair with a pile of gear and just talked: race season fandom, scrappy brands worth knowing, the shoes I'm fired up about right now, and the two-hour long run philosophy I'm using in training for Paris Eco Trail.For ultra runners and trail runners who are in it for the culture, the gear, and everything that makes this sport unlike anything else.Please give us a follow, rate the podcast, and give a review.01:23 ACTUAL trail running10:48 Ultratrail Race Season13:39 Running to "Overcome"16:23 Ciele Athletics18:39 Trail Shoe Design24:05 Scrappy Trail Running Brands30:37 Meme Culture35:08 Tommie Runz36:21 Taylor Bodin (dirt division) + Josh Bouton (meta endurance)38:27 Inky Steve, Stan Van Kemmel, Bryce Carlson, Sam LohsePresented by Kiprun.----Find us at Borderlands.cc and sign up for the newsletter.Want to run in the Salt Lake area?

If you've ever wondered how ultra running nutrition changes when races stretch beyond a single day, this episode reframes race day nutrition to better address multi-day endurance races.Jesse Rich, nutritionist to elite ultrarunners, explains why traditional fueling advice breaks down during multi-day endurance efforts. As sleep deprivation, calorie deficits, and digestive fatigue accumulate, runners must think beyond electrolytes and gels and begin considering deeper nourishment ideas like how the body burns calories during mult-day events, how long it takes to absorb them again, and how sleep, recovery, and caffeine timing all affect performance.For ultrarunners preparing for multi-day races like The Speed Project or anyone curious about how the body fuels extreme endurance.Please give us a follow, rate the podcast, and give a review.Presented by Kiprun.----Find us at Borderlands.cc and sign up for the newsletter.Want to run in the Salt Lake area?

If you spend time around ultra running, you’ve probably felt the tension around run influencers. They can be annoying in the moment—film crews at races, cameras everywhere—but they’re also inspiring thousands of people to start running, many of whom just needed that final push to move.Ultra runner and content creator Tommy Lewis joins Josh to talk about the strange reality of influencer culture in ultrarunning: being tired of the business of running while still deeply in love with the sport itself. From Western States to UTMB, they explore the balance between content, community, and the simple joy of running.For trail and ultrarunners curious about the role influencers play in growing the sport and shaping its culture.Please give us a follow, rate the podcast, and give a review.Presented by Kiprun.----Find us at Borderlands.cc and sign up for the newsletter.Want to run in the Salt Lake area?

Ultra running is professionalizing fast. Bigger prize money, more sponsors, and smoother finishes. Laz Lake is the counterbalance to all of it, and this conversation is about why that matters.In part two of this trilogy at Laz's Tennessee farm, the two go deep on what makes Laz unlike anyone else in the sport: untouched by modernization, unbothered by fame, charging $1.60 for race entry while the rest of the industry chases scale. Josh draws a line from Popcorn Sutton, the last Tennessee moonshiner, to the Donner Party, to Bigs Backyard Ultra, and somewhere in the middle of all of it, a portrait of Laz emerges that you won't find anywhere else.This one’s for the ultra runners who love the underground soul of this sport and don't want to see it disappear.Presented by Kiprun.----Listen to Scene One (the Races of Laz Lake) on Spotify or Apple or watch on YouTube.----Borderlands.cc | Podcast NetworkSign up: analog*Borderlands [new]letterWylder is now available on iOS + Android.Salt Lake Foothills Trail Races | 30 May 2026

The Speed Project is one of the most unusual events in running—an unsanctioned, no-rules relay that sends teams roughly 340 miles from Los Angeles to Las Vegas (and now across Europe from Chamonix to Marseille). Josh sits down with founder Nils Arend on a rugby field in Albi, France at midnight to talk about how TSP began and why it has become something far bigger than a race.What started as an extreme endurance challenge through desert heat, sleepless nights, and relentless miles has evolved into a powerful community. The conversation explores the origin story of The Speed Project, the transformations it sparks in participants, and how this underground event created a culture and identity that exists outside the traditional ultrarunning world.For runners fascinated by the stories, people, and ideas pushing the edges of endurance.Please give us a follow, rate the podcast, and give a review.Topics / Timestamps00:00 The Birth of The Speed Project 06:04 Creating Moments Through Running 12:04 The Role of a Curator in Running 19:02 No Rules: A New Approach to Running 25:05 Building a Community Around The Speed Project 32:38 The Evolution of The Speed Project 37:39 Navigating Challenges and Responsibilities 43:57 Nils Would Have Ended TSP without Scotty Crowe 45:57 The Influence of Daniel Dart from Time Again 56:05 Runner's World and TSP Presented by Kiprun.----Find us at Borderlands.cc and sign up for the newsletter.Want to run in the Salt Lake area?
