Rob Simmelkjaer is the CEO of the New York Road Runners, the organization that gathers 55,000 sadists every year to run the iconic New York City Marathon, among many other events. We (barely) caught up with Rob as he was getting ready to hop a flight to Japan to run the Tokyo Marathon to find out how he finds time to train, how newbies can get started, and what you need to do to let your feet forgive you after making them pound the pavement for 26.2 miles.
