There's a long answer to this question, but here's some discussion that will get you started: http://www.runningahead.com/forums/topic/1bbecf6547854ca88f80093bb6827e47 If you still have more questions (which is great!) try another post in the "Running 101" or "General Running" forums, as most people will look there for questions like this. And feel welcome to post 'early and often'! In my experience, this is an extremely friendly little online running community. Welcome aboard!
