From the publisher
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.

S1 Ep 290The Reinvention of Kiprun
Kiprun used to feel like an entry-level running brand, not one serious runners would put in the same conversation as the best trail running shoes in the sport. If you’re curious how a brand changes that perception and what it looks like when a running company genuinely reinvents itself this episode is for you.Josh sits down with Inky Steve to break down the shift they’re seeing at Kiprun through the Kipsummit Max, Kipsummit Race, and the broader portfolio now taking shape under Decathlon. They get into stigma, design, price, performance, and why this feels less like a one-off good shoe and more like a brand returning with a completely different level of intent.This one’s for runners who care about shoes, design, and where the culture is moving.Please give us a follow, rate the podcast, and give a review.Topics / Timestamps00:00 - The Rise of Kiprun04:33 - The Transformation of Kiprun Shoes09:37 - The Evolution of Trail Running Shoes15:27 - Running Shoes and Innovations18:58 - Kiprun's Kipsummit Race Shoe21:06 - The Evolution of Trail Running ShoesResources / LinksKiprun Kipsummit RaceKiprun Kipsummit MaxJosh Rosenthal on IGBorderlands.ccLa French TrailHigh TonesSubwhateverPresented by Kiprun.----Find us at Borderlands.cc and sign up for the newsletter.Want to run in the Salt Lake area?

Running helps strip away all the things we distract ourselves with and forces us to stand face to face with them.In this conversation with Mike Kratzer, a former DJ turned runner, we explore what happens when there’s nothing left to hide.

This episode explores how sobriety, loss, and identity shape the path into ultrarunning and what it actually looks like to rebuild a life from the ground up.Josh sits down with Tommie Runz to trace the arc from heavy drinking and personal collapse to running across the desert from Los Angeles to Las Vegas, and eventually into ultrarunning.

S1 Ep 285Is Ultrarunning Losing Its Charm?
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.

S1 Ep 284Is Ultrarunning Changing? Dirtbag Culture vs Luxury Running Brands
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.

S1 Ep 28210 Things I Love About Trail Running Right Now (Spring 2026)
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?

S1 Ep 279Ultra Running Nutrition: An Elite Coach Reframes Fueling
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?
