You say pa-TAY-to, I say pa-TAH-toe … some differences are merely how we use language (the eternal pop vs. soda debate, for example), while others are more meaningful.

In an ideal runner's world, every step of every mile would be 100 percent pain-free. No aches, no twinges, no lingering soreness from yesterday's workout. The reality is that many runners constantly deal with a slight (or not so slight) disturbance—a tender foot, a tight hamstring, a whiny knee. While these nagging issues often aren't serious enough to require a time-out, they are annoying, especially when they don't let you fully enjoy your time on the roads.
