Feeling so unprepared!

Ahh - the marathon is less than a month away and I really feel so unprepared! I know I've been training a lot, but when I look back on the past 4 months, it all feels like such a blur.

This weekend is our big run - 21 miles along the marathon course. Most of the charities participate and there's even a camera crew out to take pictures of us along the way. A bus pics us up from our typical starting point and brings us out to Hopkinton for an 8:00 a.m. start. They call it the "dress rehearsal," we're even supposed to wear our bibs to make sure they're not horribly uncomfortable on race day (although, what do we do if they're horribly uncomfortable during this 21-miler?).

I'm really excited but also really nervous - what if I don't eat a good enough dinner the night before? What if my new sneakers really start to hurt? What if I can't do it!? What if I don't raise all my money!? What if what if what if!!??
