Like most new physical endurance based challenges, running is going to be something you will most likely fail at miserably on the first try. You will lace up your shoes, head out the door, and three minutes in, lungs burning and heart pounding, your mind will begin tossing out questions: "Isn't this supposed to be fun? When does it get easy? Where's the runner's high? When will I be able to talk? What it so darn great about running? I just want to stop and lay down!"
