I ran the philly marathon barefoot today. I saw a few vibrams and lots of newton but i think I was the only barefooter. There was a man running the half barefoot. He gave a nice talk at the expo. My time was 4:40:42. Not great but i am happy with it since i was not able to run the last 3 weeks due to Sandy and a poorly timed vacation. Since my training was not perfect my form broke down the last few mile and I have a blister on my right heel of all places. Must have been heel striking or landing flat foot and rolling.
