Life barrels on like a runaway train

I've got my big 5K tomorrow, and I gotta tell you, I'm a little nervous. I don't know why; it's not like I really have any goals to meet. Mainly, my goals are: (in no particular order) to finish, to not finish last, to not fall, to not puke, and to not die. All in all, pretty reasonable goals, I think. Yet, still there are the nerves. Jen says she gets them before every race, too, so I don't feel quite as freakish. It may just be a Jen thing. Or it may because they call the whole thing a "race." I'm not racing anybody, people. I'm trying to run a predetermined length of road without humiliating myself. That's all.
