I have seen this mentioned in a couple of different threads now. My understanding was that it is against USAT rules to go shirtless at any time during a race. Am I wrong? Also, does shirtless apply to women in sports bras or a woman wearing a one piece bathing suit under her tri shorts?
I confess that I have not read the rules but during the racers' meeting before our local sprint triathlon last year, we were told that anyone not wear a shirt would be disqualified. Even though it wasn't a USAT sanctioned race, they said they wanted us to comply with USAT rules. I guess I should go and read the rules. What a drag!
