Video: Interview With Dean Karnazes - The Ultramarathon Man

Want a little inspiration for a weekend run? Look no further than this interview with Dean Karnazes, probably the most well known ultra-runner in the world. Dean talks about how he got started in running, what his daily running routine consists of and his passion for running really long distance. This is a guy, after all, who has run more than 250 mile (400 km) non-stop. And yet, he still says he's just an average guy.
