Should I go for it?

I just found out that there is going to be a half marathon at 8am the Sunday after Thanksgiving at the Stennis Space Center in Mississippi. Given that I ran 12 miles two weeks ago, 6 miles last Sunday, and am planning on making it to 13 this weekend, I know I can do the distance, although I would have preferred to run 13 miles prior to my first half marathon race (I'll probably do no more than 10 miles this weekend if I do the 1/2 though because you are supposed to taper the week before a race). It would also be on my way home from Thanksgiving with my family in Gulfport anyway, and I would certainly burn off Thanksgiving dinner! :)
It's not what I planned to do, but since I'm so far ahead on my training (I started my training earlier than I needed to so I would have some leeway in case I needed it) I am pretty sure I'll be fine. The race description also says that this is a good one for beginners....
As you can tell, I'm totally talking myself into it, but I'll blog my final decision when I make it. One issue is that it cuts down the time I get to spend with my family, but maybe I can get them to come cheer me on. Also, when I am at my family's house, my nutrition tends to suffer. We eat out a lot because my mom and I both tend to view visiting each other as an occasion for going out, and my parent's kitchen tends to be red meat and no-carb land (they love Atkins, and don't get me started on how much I disagree with them regarding that diet). These issues are fairly minor though, I can come equipped with oatmeal and whole wheat pasta or quinoa (at least my parents have plenty of frozen veggies)- I just have to be diligent about how I fuel in the few days prior to the race and try to stay away from the junk food. Except on Thanksgiving day of course. I'm totally allowed to be a pie eating monster then! :)

And...after about 5 minutes of consideration I've decided that I'm totally going to run the race! Racing is so much fun! I'm excited!!
