Please note that if you are running in an USATF officially sanctioned event you cant run bare chested. I was in a mile race last week and the official made some guy put on a shirt before competing and said that the rules and regs prohibit racing bare chested.
I don't have the USATF rule book in front of me, but I believe it allows for shirtless racing in 5K and longer events. Although that might be road racing only.
As far as I know, the rule book does not mention that you will look like a moron if you don't wear a shirt.
