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 291Why Running Changes You (It’s Not Just Fitness) with Raz Rauf
Trail running and running culture go beyond training plans, races, and performance. Raziq Rauf explains why running isn’t just a sport, but a reflection of identity, place, community, and modern running culture.Raziq is the author of This Is Running and writes the newsletter Running Sucks. In this episode, we talk about running as culture, not just competition: place, community, creativity, solitude, fashion, consumerism, and why a run can change the person who started it.

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?
