I just ordered my shirt today - as a matter of fact, I ordered two (different sizes - LOL), my true size and one size larger. There's no shame in my game. I am looking forward to the challenge. I feel very excited and even if I don't complete the entire 100 miles, that's okay, but I will do my best to finish. I needed this to get me motivated so I would get off my rear end after four and a half months.
