Go Faster Hair

Had my hair French platted for my run tomorrow. Thought it would keep it out of my face. I've never worn a platt in my life...not even as a kid. Mind you I always had short hair because I swam. It was easier to deal with.
I'm hoping it will be go faster hair. I have a three hour cut off time. Being my first, probably last, half marathon I have no idea what I'll do.
I hear it's a fast course and people go there to get PB's. There will be a lot of Billy Wizzes. I hope I'm not last.
Nervous already.
