She was a sprinter from Bahrain.
It's funny that you mention that. I was commenting to my wife how there were some sprinters that were wearing sleeves. We were like, "How is that supposed to make you faster?" I said, "Well if wearing a sleeve makes you faster, why don't they wear full bodysuits?" Then we saw that runner from Bahrain. I was like, "See? There's someone that is going all the way with the sleeve thing." Then it turns out she was just covered up for religious reasons.
Did you hear her barking like a Pomerainian on that last 100 meters? Funny as hell.
