I really can't believe that BOTH the USA men's and women's relay teams DROPPED their batons during their races and are completely out of the running now.
What a horrible feeling that must be for them.... to train SO hard for SO many years and then to make such a careless (and preventable!) blunder that ends the whole thing in a split second.
I think I would probably throw up from self-disgust if that happened to me.
I'm sure they are still in shock.
