The term "jogger" is offensive to many a runner here in the states; I don't know about the stigma elsewhere.
I run 30+ miles a week, most weeks, although it's more difficult to get the mileage in during semesters.. I absolutely hated running in high school when I played football/basketball...that's how they punished you! But, I caught the bug when I was maybe 22-23 and can't stop now (I'm 25). I also regularly run 5/10K's - too much fun!
