Run v. Jog

Q: What is the difference between the words “run” and “jog”? Or more specifically, what is the difference between a “runner” and a “jogger”?

A. Ten years ago when I was a lot faster and I’d pass a group of moms and their kids, one of the moms would call to her kids, “Watch out for the runner.” Now they say, “Watch out for the jogger.”
