Marathon Man

Dean Karnazes is an Ultrarunner. Meaning he is crazy. He has completed running feats such as running 50 marathons, in 50 states, over 50 consecutive days, concluding with the NYC Marathon (lucky!). He's run across Death Valley as well as the South Pole. He's famous in the running world for his extremely long run runs and the severe conditions in which he runs them.

Now he's done it again. This time, on the Summer Solstice, he ran for 24 consecutive hours on a treadmill suspending in the air in Times Square!
