In this wide-ranging and deeply insightful conversation, Brian Halligan and Andy Newell sit down with Dr. Øyvind Sandbakk—one of the most influential figures in modern endurance training science. From his early days as a competitive skier to his role as a professor, researcher, and architect of much of what the world now calls the “Norwegian training model,” Øyvind shares the winding path that led him from athlete to coach, scientist, and mentor to some of the best endurance performers on the planet. The discussion blends real-world coaching wisdom with decades of applied research, offering listeners a rare look behind the curtain of elite performance development.

The episode dives deep into how training theory actually gets built (not from shortcuts or trends) but from systematic observation, precise intensity control, and a culture of shared learning between athletes, coaches, and scientists. Øyvind explains why concepts like threshold training, intensity zones, and “polarization” are often misunderstood, and why training precision and intention matter far more than buzzwords. Using examples from cross-country skiing, biathlon, running, and triathlon, he breaks down what separates good athletes from great ones, and why quality, consistency, and recovery always beat chasing extreme volume or fashionable methods.

Finally, the conversation turns toward coaching philosophy, athlete development, and long-term success. Øyvind offers practical guidance for junior athletes, developing seniors, and coaches working without access to labs or advanced tech: emphasizing training diaries, honest feedback, simple monitoring tools, and trust-based coach-athlete relationships. The episode closes on a powerful reminder that coaching isn’t just about creating champions, but about helping people grow, learn, and master their own potential. Whether you’re an athlete, coach, or endurance nerd, this episode is a masterclass in how elite performance is actually built.
