untill you do your first race!! then you are a PRO!!!
Seriously though, its my opinion that what sets apart a "recreational" runner (one who goes out and runs for fun, for exercise, just to get out, 3 or 4 times a week, not too concerned with distance and speed) vs an intermediate or more serious runner and up is that with the more serious runners, every single run has a purpose, a goal behind it...be it a long run to build endurance, a tempo run to work on building the lactic acid threshold, a speed workout, or a "race pace" run to build muscle memory at the pace you want to race a given distance at.... every week i incorporate every single one of these runs into my training schedule.....its very sad, i hardly ever get out and just "zen" run anymore!!! i feel like i have to make every run count...
