Marathon! (Well, 1/2)

I am so excited!  I signed up for my first half marathon.  I still can't believe I'm actually going to do this.  No, I'm sure I won't run all of it, but I definitely will complete it.  I'm planning to run the Rock -n- Roll half marathon in Savannah this fall.  Its actually my birthday gift from my grandmother.  If you had told me two years ago I would want registration in a half marathon for my birthday, I would never have believed you.  Its completely official.  I'm registered and everything.  Wish me luck!
