What did I get myself into??

So after a few glasses of wine about 3 weeks ago, I agreed to run a 5K race with my sister in law. Tomorrow is the big day and I'm not going to lie...I'm nervous. I know, I know, I know, it's only 3 miles...but I think this was a little aggressive for someone who does not run! Besides, once I peed on that stick...I avoided every form of excercise! :) So now I'm using muscles that I forgot I had! But, it's a race darn it and I'm going to run. I've been attempting to run the last few weeks, and I have gotten up to 2 miles without feeling like death, so I might be able to run the full 3.1 miles. We will see! Wish us luck!!
