Barefoot in a half marathon???

Hello! It's been a while. Life has really interrupted this bloggin thing and I'm still looking for my muse. Anyhow........ I'm running in the Newport Half Marathon tomorrow and I'm thinking of trying my first barefoot half. My longest barefoot was a 10k earlier this summer. It was great. The paved trail was fine on my feet. I'm a little worried about my ability to push that to 13.1 though. I'm not really sure what the roads are like either. At this point, I'm ganging to say f-it and chuck the shoes. I'll carry my huaraches in case my form goes to hell. Here goes nothing! Cheers!
