There really is only one reason to run: A poorly fed tiger is in pursuit of your hindquarters. That right there is a damn good reason. Also, maybe a flood. Or if you’re on fire (although it’s actually better to stop, drop and roll, unless, of course, the tiger is behind you. In which case, just keep running!) But truth be told, I can think of very few reasons — logical, good, rational reasons — to go out and pound the pavement. To wear those short running shorts. To get blisters. To hear endless people shout out their car windows, “Run, Forrest, Run!” To put one foot in front of the other for hundreds, if not thousands, of steps so you can get from point A to point B. And I say all of this as a runner myself. As someone who loves — yes, loves — to run. But someone who also can’t quite figure out why in the world he does it.
