I'm not that serious with my running, last year I had starting number 40000ish and finnished at around 1.50, the heat was crazy(tons of ambulances) making everyone else run slow so I was a bit dissapointed with my time. Next year I am aiming for 1.40 ish time but finnishing barefoot seems like a much cooler goal. Maybe I can combine these goals, when I run barefoot I tend to run a bit slower but get less exhausted, maybe I can keep a higher pace if I push myself.
I will have some support around the race so I could give them a few pairs of VFF and stop where they are and put it on if needed. I am used to running with a pair of shoes in my hands, but it looks much more cool if people can see that you really run barefoot the entrie race, not just when they happen to see me.

I will try to run on the track a few times to get my brain to remember where not to step. Maybe it's a good idea to get a few friend to run close to me when training barefoot to get used to the crowding.
Maybe people will see my bare feet and run more careful around me?

Anyone with experiences? Brainstorm what could go wrong!
