The Marathon Man

Let me start out by saying I am not a runner. When I was young I did run track but nothing longer than the 300-meter hurdles. If I have to farther than 300 meters I am taking a car, a train, a bus, or maybe even a plane. Years of playing sports have left my knees in bad shape. Every time I kneel down and try to get back up it sounds like a Rice Krispies commercial. So given these facts, why in the world would I even consider signing up for a 5K...
