Greetings, SuperFriends! Today we are honored to have with us Dean Karnazes. He's a speaker, a bestselling author, an athlete, and an entrepreneur. TIME Magazine named him one of the top 100 most influential people in the world. Why, you ask? Because he is an ultra marathoner... not just any ultra marathon, by the way: he has run three hundred and fifty CONTINUOUS miles... not going sleep for three nights. He's run the Sahara Desert at 120 degrees. He has run 50 marathons in 50 days. He's biked for 24 hours straight. He swam San Francisco Bay... I could just go on basically and spend the entire episode talking about all the insane feats of endurance and athleticism that Dean has done. But I won't because I want you guys to hear from him. In any case he's been on The Today Show, 60 Minutes, Late Night Show, CBS, ESPN, CNN... basically all the networks! Again, I could spend the entire episode. I wanted to get Dean on the show for very obvious reasons. He is literally a superhuman. He has a lot of very interesting things to say about tenacity and about fitness. About training... well, he has some things to say that will surprise you. Some things to say that definitely will NOT surprise you. And in general we just hit it off and had a really great conversation. I hope you guys enjoy it as much as I enjoyed creating it!
