Am I crazy??

Quite possibly! I just signed up for my first half marathon!! I've NEVER done a race...ever. I was working out with my friend last night and said "I'd like to do a 5k someday" and she said there is a race in September, lets do it...she was already signed up, so I said...OK!! Well, its NOT a 5k! Its a half marathon! Call me crazy, but I signed up and Im gonna finish it! I know I wont be able to run the whole way, or even half of the way, but my main goal is to just FINISH!! Wish me luck!
