During the women's 200m semifinal only three runner's could qualify, so you would think you'd give it 100 percent the whole race. Apparently, Jamaica's Shericka Jackson didn't get the memo. For some INSANE reason she starts to jog at the end of the race! That jogging cost her a spot in the final because she came in fourth! She missed out on the final by four one thousandths of a second!!!!
It is incredible to watch this and not be able to comprehend what she was thinking!
