The 2013 New York City Marathon is upon us, and ASICS and Vitro are challenging ordinary people to try to match Olympian elite runner Ryan Hall's pace -- even if just for a minute. The brand is a marathon sponsor, and has set up a treadmill onto an ASICS truck that runs at only one speed: an astonishing 4 minutes and 46 seconds a mile -- also Mr. Hall's pace. The treadmill will tour New York City and challenge people to try it out, with a safety harness in place.
