As most of you know I have run some marathons and I read the confessions of an all night runner. This person is very inspiring:

Dean Karnazes finished running 50 marathons, in 50 states, in 50 consecutive days with the New York City Marathon. Now he is running home, across America, to San Francisco. Think Extreme Running, think Forest Gump! His goal is to inspire people to get healthy and achieve their personal best.
