What does true longevity in the sport of ultrarunning actually look like? In this episode, we are joined by the incredible Mario Zuniga (known on Instagram as @zoonigamario). Mario proves that age is just a number when it comes to tackling some of the most iconic, grueling endurance events in the country.

What makes Mario's resume mind-boggling is that he accomplished his greatest running milestones all after turning 50 years old. We dive into how he has successfully completed America’s oldest ultramarathon—the legendary JFK 50—an astonishing 10 times, earned 9 Boston Marathon finishes, conquered the rugged terrain of West Virginia's Highland Sky 40 Mile 5 times, and survived the infamous ratcheting pain of The Barkley Fall Classic 3 times. Mario shares his secrets for injury prevention, maintaining high-level consistency across decades, and keeping the passion alive when the trails get steep.
