If you run for exercise or sport or both, do you prefer to be called a runner or a jogger? One Runner's World reader asks expert columnist Miles what word is most appropriate. Definitely "runner," he says.

"Jogging implies that you lack passion and commitment, that you're out there on the road in $130 running shoes simply for show, that you could take the sport or leave it (and often do leave it)," says Miles.

Ask any runner and you'll hear the same sentiment, Miles reports. You'll hear that those who "run," not "jog," do so to push their limits and live healthier lives. Run a six-minute mile or a 12-minute one -- it doesn't matter. It's still called running. Not jogging.

I don't really care what I'm called. Although I guess when I talk about myself and what I do for exercise, I rarely say the words "jog" or "jogger." How about you? Are you offended by "jogging"?
