This is sort of like racing up Mount Sentinel to the M. More than 500 people are putting on their running shoes to get ready for tonight's annual sprint up the 86 floors of New York City's Empire State Building. They'll actually be climbing 1,576 steps. Participants are from around the world, and they include top athletes. The fastest climbers can get to the 86th-floor observation deck in just minutes. We’ll have the winners time for you Thursday morning on Craig & Al.
