Day Before the Race Jitters

Did I eat too much crap? Did I drink enough water? Do I have all my gear? Are all my electronics charged up? Do I know where to park? Will my wife make me late? It's supposed to rain, what do I need to do? What if I have the runs? What if I miss my wife and she has my GU? What if I forget something? What if I over sleep? What if I can't sleep? What if I start too fast? What if I start too slow? What if I don't finish? Do my legs ache or is that just in my head?

Do I need to tell you I am a tad nervous?
