Okay, I know this is going to sound like a silly question, but I really don't know the answer. What is the difference between running and jogging.
I know at 4 mph, I am really just jogging I guess, but I want to work up to running so whats the difference? I am heavy and when I run or jog, it feels like running cause it's hard and I can't breath, but for others I am probably just at a fast job, or even slow jog.
I guess I just want to know when I can actually say I am running and not just jogging, or does it really matter.
