The Accidental Business Owner Who Built the Science of Endurance Fueling

Andy Blow didn't set out to build a company. He set out to stop ending up in the medical tent. As a triathlete who kept collapsing in the heat, Andy discovered that electrolyte loss is deeply individual, got a sweat test, changed his nutrition, and realized that what he needed didn't exist for other athletes either. Fifteen years later, Precision Fuel and Hydration is one of the most trusted names in endurance sports nutrition, working with elite athletes from Rachel Entriken to Caleb Olson to the Ironman World Championships. Andy joins Long Run Labs to talk about the science, the business, and everything in between, including what it actually took to survive long enough to build something real. Jon and Andy chat about: * why Andy kept ending up in the medical tent and what it taught him about individual fueling * how Precision Fuel and Hydration started as a sweat test, not a product * why separating fuel from hydration is the foundation of their entire system * the three levers every endurance athlete needs to understand: carbs, fluid, sodium * what amateur athletes consistently get wrong about race nutrition * the Tim Noakes debate and how to think about high carb fueling * Rachel Entriken, Cocodona, and what longitudinal field data actually shows * why the business nearly died more than once and what kept it going * how their Ironman partnership started with a confrontation with Ironman's legal team * building athlete rosters around authenticity, not follower counts * the F1 years and what endurance sports can learn from motorsport * the future of trail race broadcasting and live data * why Andy stepped out of the CEO role in January and what that transition looked like * what he believes now that he would have laughed at in 2011 Stay connected: Precision Fuel & Hydration - Dial your fueling in this year.

Des Linden: Build the Audience. The Deals Follow.

Des Linden has spent two decades figuring out how to build a career that outlasts the finish line. The 2018 Boston Marathon champion joins Long Run Labs to talk about the business of being an endurance athlete, what loyalty actually looks like in a long-term brand partnership, and why non-endemic deals are some of the most underrated opportunities in the sport. The conversation covers the real mechanics of how Des thinks about partnerships, content, and the transition from road to trail, plus an honest look at what it takes to stay relevant and build something lasting when the competitive chapter starts to wind down. Jon and Des chat about: * how Des started seeing the business side of running as early as 2011 * what 20-plus years of loyalty with Brooks actually looks like in practice * the difference between endemic and non-endemic brand deals and why the slow burn pays off * why host-read, unscripted ad reads outperform scripted ones * the digital twin of Des's heart and what TCS built with it * CPMs, pilot deals, and how to let the math make the case for you * YouTube as a long-form storytelling tool, not a vlog machine * the trail running boom and why Des is entering that space carefully * gravel running as an untapped middle ground for brands and audiences * financial literacy as one of the most overlooked gaps in professional running * angel investing, equity deals, and when skin in the game changes how you show up * why Yeti Coolers is the dream partnership Des hasn't pitched yet This episode is supported by: The Huddle: If you're at the point where going at it alone isn't working or you're ready to level things up in your business, go to https://findmyhuddle.com/ [https://findmyhuddle.com/] and fill out the application Popfly: If you're a brand trying to reach outdoor, travel, and adventure audiences, Popfly is where to do it.

Why the Future of Endurance Brands Is Community, Trust, and AI | Randi Zuckerberg

Randi Zuckerberg has spent her career at the intersection of technology, media, storytelling, and entrepreneurship. But in recent years, endurance sports have become just as central to how she thinks about leadership, business, and personal growth. Fresh off a 10-hour PR at Cocodona 250, Randi joins Long Run Labs to talk about why ultra-endurance racing and entrepreneurship require many of the same skill sets: resilience, adaptability, team building, and learning how to stay calm while solving problems in real time. The conversation also dives deep into AI, the future of media, niche communities, brand trust, and why emotional connection is becoming one of the most important differentiators in business. Jon and Randi chat about: • how Cocodona became a team effort instead of just a solo race • the overlap between endurance sports and entrepreneurship • her “pick three” framework for prioritization • angel investing at the intersection of AI and endurance sports • why she invested in brands like Janji and Laurel • how AI is reshaping startups and software development • the future of niche media and long-form content • why trust and emotional connection matter more than ever • how brands can use AI to better understand community behavior • the difference between external validation and intrinsic motivation• redefining success in your 40s • why endurance sports changed her relationship with ambition This episode is supported by: ⁠The Huddle⁠: If you’re at the point where going at it alone isn’t working or you’re ready to level things up in your business, go to https://findmyhuddle.com/ and fill out the application ⁠Popfly⁠: If you’re a brand trying to reach outdoor, travel, and adventure audiences, Popfly is where to do it.

Rethinking Outdoor Apparel for a Warming World | Doug Waters

Doug Waters didn’t set out to build another outdoor apparel company. He set out to solve a problem he kept running into himself. Doug is the founder of Terlingua Threads, a hot-weather adventure apparel company focused entirely on performance in extreme heat. After careers in consulting and the automotive industry, Doug found himself questioning why so much outdoor gear was still designed around cold weather while races, hikes, and outdoor adventures continued getting hotter. Jon and Doug talk about what it actually looks like to launch a product-first brand from scratch, why climate adaptation is becoming unavoidable in outdoor sports, and the realities of bootstrapping a physical product business in 2026. Jon chats with Doug about: • visiting all 63 U.S. national parks • how Big Bend National Park sparked the idea for Terlingua Threads • why most outdoor apparel still prioritizes cold weather • designing apparel specifically for 90°+ conditions • balancing performance, safety, and sustainability • building a brand around natural fibers instead of synthetics • bootstrapping vs. raising outside capital • why retaining creative control matters • product-led growth and learning from elite endurance athletes • using craftsmanship and storytelling instead of AI-generated marketing • the future of small business and independent brands This episode is supported by: ⁠The Huddle⁠: If you’re at the point where going at it alone isn’t working or you’re ready to level things up in your business, go to https://findmyhuddle.com/ [https://findmyhuddle.com/] and fill out the application ⁠Popfly⁠: If you’re a brand trying to reach outdoor, travel, and adventure audiences, Popfly is where to do it.

Why Entrepreneurs Stay Stuck (And How to Actually Move Forward) | Christian Rawles

Christian Rawles didn’t just build a brand in the outdoor industry, he spent nearly two decades learning what it actually takes to run one, eventually buying and leading the business himself. Christian is now an executive coach working with entrepreneurs who want to build businesses that align with their values, not just scale for the sake of growth. His work focuses on clarity, self-awareness, and helping founders close the gap between where they are and where they want to be. Jon and Christian explore what it really looks like to build a career intentionally, and why so many entrepreneurs stay stuck even when they’re doing everything “right.” Jon chats with Christian about: • starting at the bottom and learning how a business actually works • working for free or cheap to create career inflection points • why working in the outdoor industry isn’t always what people expect • how he transitioned from founder to executive coach • the difference between being stuck and being unclear • the “gap vs. gain” framework and why it changes everything • fear of success vs. fear of failure • defining success beyond money and metrics • the role of presence, gratitude, and self-awareness • why entrepreneurs need new definitions of success Stay connected: Christian's Website: https://www.christianrawles.com/ This episode is supported by: ⁠The Huddle⁠: If you’re at the point where going at it alone isn’t working or you’re ready to level things up in your business, go to https://findmyhuddle.com/ [https://findmyhuddle.com/] and fill out the application ⁠Popfly⁠: If you’re a brand trying to reach outdoor, travel, and adventure audiences, Popfly is where to do it.
