Going for a run...all of me's

So, I started running again... I've always been an avid gym-goer, but running has never been my thing.  However, since my family and I moved to the country, it's started to seem like a great exercise option...I have more open road space than anyone could want, and I don't have to drive all the way into town to hit the gym. Running, to me, is a great many things...It is not, however, fun. Below is a transcript detailing a conversation in which I partook with my NikePlus iPhone app, my self, my body, and my common sense. Self: Okay...I can do this, four and a half miles is really not that far, and I did four last week. Sense: Yes, but it wasn't ninety degrees then. Self: Oh, whatever...it'll be fine. Sense: Oh sure, just dismiss me...that worked out well when we were in college. NikePlus(voice of a lovely, kind woman): Begin workout. Self: Woo-hoo...Let's go! Two minutes later... Nike Plus(voice of a firm, driven coach): Point two five miles completed. Self: That can't be right...I was faster than this in high school! Sense: And thinner, and with more hair.... Eight minutes later... Body: Our legs are starting to hurt....are you sure you're doing this right? Self: Of course I'm sure...I've been running since I was three years old...Liam even knows how to run. Sense: He's also afraid of the shadows in his room...oh wait...so are you. Self: They look as if- NikePlus(voice of drill instructor from Full Metal Jacket): one point two miles completed...move your fat ass. Forty minutes later... Self: This...bad...idea Sense: I tol- Self: Oh, shut up! Body: Full system shut down in...five...four... NikePlus(voice of the devil himself)- point zero one eight miles to go....you're not done yet! Self: Isn't this where I'm supposed to get runner's high? Sense: Runner's high is a myth propagated by runners trying to convince you that what we just endured is a worthwhile and pleasurable activity. Self: For once, I think we agree.
