Dean Karnazes, author of  Ultramarathon Man: Confessions of an All-Night Runner, was recently named by Outdoor Life Network as one of the Ten Ultimate Athletes. He has pushed his body and mind to inconceivable limits: ran 262 miles non-stop, swam across San Francisco Bay, ran a marathon to the South Pole, mountain-biked for 24 hours straight, ran across Death Valley in 130 degree weather. He reveals how he merges the solitary, manic, self-absorbed life of ultrarunning with commitment to wife and family. Meet this local man with uberjock's body, teenager's energy, and a champion's wisdom.
