Running: short or long

As I was running in Lincoln Park this morning I wondered if the distance of the run made any difference. My run today was short, in fact my longest runs would probably be considered short by some runners. However I do run different distances on different days. In one sense the distance is relative, and my long runs are only long when compared with my own shorter runs. In another sense, more important perhaps, the distance does not matter. For it is the running that matters, the action itself. Movement is key and if I do that regularly the distance will take care of itself - so to speak.
