In this episode, I sit down with Matthew Kellenberger—former military soldier, ultra-endurance athlete, and all-around powerhouse in the world of multi-sport endurance! From the battlefield to the racecourse, Matt has forged a path built on discipline, perseverance, and a relentless hunger for pushing limits.

We dive deep into his journey from military service to ultra-running and triathlons, uncovering the mental toughness it takes to thrive in high-stakes environments—both in combat and on the course. Matt’s passion for endurance sports isn’t just about finishing races; it’s about showing up, pushing through, and proving that the human spirit is tougher than any obstacle in its way.

But that’s not all—Matt is also a dedicated advocate for military veterans, using his platform to support those who’ve served and to help others find healing and purpose through endurance sports. We talk about the importance of camaraderie, finding your “why,” and what it really takes to embrace the grind day in and day out.

Oh, and did I mention? This episode is packed with high-octane energy, a few pseudo-military Chuck Norris-style jokes, and a whole lot of pure, unfiltered inspiration.

So lace up, tune in, and get ready for some serious motivation. This one is for the warriors, the grinders, and anyone looking to break through their own limits. See you out there! 💥🔥
