Want to be clear wrote:
Hobby means something you do for fun and are not paid to do. People whose full time paid job is to run (runners with professional contracts) are not hobby joggers. Collegiate runners with scholarships who run on the varsity team are not hobby joggers.
Everyone else who runs is a hobby jogger. Do I have that right?
You are close. If you are on a school team and travel you would not be an HJ.
Post-collegiate with some type of sponsorship Could be considered part time.
Most others would be Hobby Joggers.
Some people collect stamps, some build model planes and some jog. The ones who call themselves Hobby Runners are just HJs who put more time and effort into their hobby.
