To kick off Season 2 and celebrate the 20th running of the Route 66 Marathon we’re joined by none other than Dean Karnazes — ultramarathon icon and global ambassador of endurance.

Dean ran in the very first Route 66 Marathon back in 2006, and in this episode, he shares his memories from that inaugural event, how the Tulsa course compares to some of the world’s most extreme races and what keeps him going after decades of pushing physical and mental limits.

Plus, host Kevin Green shares a quick update about the podcast's evolving focus and how it is growing beyond ambassadors to highlight the entire Route 66 running community.
