·23 min·2 clips

Dean Karnazes ran 30 miles drunk in silk underwear on his 30th birthday, sparking his ultra-running career.

This episode features an interview with ultrarunning legend Dean Karnazes, conducted by hosts Leti and Ryan at the International Running Expo in Amsterdam. Karnazes is renowned for pioneering ultrarunning in the 1990s and completing extraordinary feats like running 350 miles in 80 hours. His career highlights include winning the Badwater 135-mile race in Death Valley and completing the 4 Deserts series. Karnazes recounts beginning his ultrarunning journey on his 30th birthday by leaving a San Francisco bar drunk and running 30 miles to Half Moon Bay in silk boxers and leather shoes. He describes a pivotal moment during that run where he felt a spiritual calling that he was "made to run." After that night, he quit his corporate job with an MBA and pursued running full-time, later authoring a bestselling book. His partnership with The North Face began in 1998 when they approached him after a race to help design the first dedicated trail running shoe. In 2006, The North Face funded his expedition to run 50 marathons in 50 U.S. states over 50 consecutive days. He currently serves as the ambassador of global Greek tourism, focusing on sports tourism by leading running camps in Greece that combine cultural visits with daily runs up to 10 miles. Karnazes has run over 300 marathons across all seven continents, twice. He shares his recovery methods, which include ice baths, compression gear, and active recovery like a short shuffle the day after a race. For nutrition, he practices time-restricted fasting and follows a very low-carbohydrate diet, advising runners to "listen to everyone, follow no one" and experiment. A memorable story involves him ordering a pizza during a 200-mile solo relay, requesting an unsliced thin crust to roll and eat while running. He notes that gastrointestinal issues are a common reason for DNFs in ultramarathons and cites a runner who completed the 153-mile Spartathlon using only liquid nutrition. Karnazes finds that running provides clarity for solving business and life problems, and he emphasizes authenticity, perseverance, and networking for business success. The tone is conversational and inspirational, blending personal storytelling with practical advice on endurance and entrepreneurship. This episode would appeal to runners interested in ultramarathon history, endurance nutrition, and career pivots, as well as entrepreneurs seeking motivational stories. Listeners preferring highly technical training discussions or shorter, news-focused content might find it less engaging.
