Why am I doing this?

Okay so I would like to tell you all that I believe I am now officially insane. I have registered to run the 5K in May, and I ran/walked 3 miles on Saturday in anticipation of...anticipating it....lol My legs still hurt a little from it and I even got a horrible time (at least, in my opinion): 45 minutes! I'm excited for the race and all, but I'm not especially looking forward to the prospect of the pain and the training beforehand. Oh well, it's very good motivation for me not to become a couch potato and such. Plus, I was running next to Nicole who basically is a gazelle while she runs, and while I won't ever have as long of legs as her, I can achieve running next to her without feeling as though I'm going to die/pass out (whichever comes first).
So...here I go! Wish me luck!
