Dean Karnazes is one of the most iconic endurance athletes of all time—and for good reason. He’s run 50 marathons in 50 states in 50 days, raced across deserts, mountains, and frozen tundras, and helped bring ultrarunning into the public consciousness. But Dean’s story runs far deeper than race stats.

In this episode, we explore the history of ultrarunning—from its roots in ancient messengers to its modern resurgence. Dean shares how he got started, what pulled him back into running on his 30th birthday, and why he’s stayed in the sport for decades while many burn out.

We cover the mindset that’s allowed him to go the distance, the toll (and gift) of solitude, how he’s kept his body healthy through relentless effort, and what’s still pulling him forward. We also dive into his upbringing, his Greek heritage, and how culture, family, and purpose all play into his enduring passion for movement.

Whether you're an ultra veteran, a weekend runner, or just someone seeking inspiration—this episode will light a fire in you.
