"Human Machine"? Maybe so, in many respects. But I think that title sells David Goggins short. He's a little bit controversial in the ultra community, for several reasons, and he often speaks his mind when questioned; his views aren't always popular or what people want to hear, yet they are often accurate. No, he's anything but your stereotypical runner, but his authenticity makes me a fan.
Another reason I'm a fan? Along with being an accomplished ultramarathoner, Goggins is also an active duty Navy SEAL who has completed BUD/S training (Basic Underwater Demolition/SEAL training) three times (once to become a SEAL, twice just for the challenge!) and a veteran of the war in Afghanistan. Though he is in a whole-other-world catagory of athlete than I am, he runs and trains for many of the same reasons that I do. The video below explains some of those reasons.
I've enjoyed watching his career from afar and his continued notoriety in the media ("Runners World" and "Outside" magazine, just to name a couple). Recently, I've found it inspiring to watch how he is dealing with his most current challenge, recovery from heart surgery to repair a hole in his heart that he has had since he was born and never knew it was there. A guy who had not missed a day of training for YEARS, now has to deal with being unable to train until he heals - if that doesn't present an opportunity to bring out your best, I don't know what does.

At any rate, enjoy the vid!
