Running is real and relatively simple — but it ain't easy. It's a challenge. It takes work. It takes commitment. You have to get out of bed, get out the door, down the street. You have to risk getting cold, wet, or too hot. Maybe whack some over-zealous hound on the snout — or 'Hot Rod Harry' on the hood — every now and again. And, of course, you have to take your very first run.
