Everyone has business trying to run a race like that. Some should try to prepare better, but frankly I don't care if they finish dead last. Just finish and put forth the effort rather than sitting on the couch.
Just my feelings on the matter. I'm working on it, but I can hardly work a gas petal right now with this pain. I'm hoping it's just a charley horse and will be o'k after a day or two. I've been babying it when running the last week or so, yesterday it just went out like someone hit it with YE's stick.
