I wish that the sprinters would go shirtless, unfortunately the ones who take their shirts off weigh about 120 pounds and look HORRIBLE without their shirts on. As a coach I do not care to look at those bags of bones running around the track. But a nice muscular sprinter, now that would be nice. But they keep their shirts on.....or wear sleeveless shirts.
I don't care one way or another, and I know that for most kids, it felt great tobe outside in the sunshine without a shirt on. Now yesterday, it was WAY too cold for that nonsense.
Girls can run in their sport bras if they want...
