Dean Karnazes is the author of Ultramarathon Man: Confessions of an All-Night Runner, a ten-time Badwater finisher, a ten-plus-time Western States finisher, and the guy who once ran 50 marathons in 50 states in 50 days. Buzz catches up with him in Athens, where Dean has spent the last three years living out his Greek roots, halfway between the city and the town of Marathon itself.

They get into Pheidippides and the 153-mile run to Sparta that Herodotus documented as history's first race report (hallucination included), why Greece is the best trail running destination almost nobody visits, the night Dean fell asleep mid-stride 350 miles into a run, the pizza he famously ordered to a moving target, and how he trains and eats to keep racing ultras at 63.
