The runoff for the third and final spot for the women's 100 meter event at the 2012 U.S. Olympic trials will be determined following the finals of the women's 200 meters. The reason for the delay in the runoff is that Jeneba Tarmoh and Allyson Felix are both entered in the 200 meters. The announcement could come either Saturday night or Sunday morning to determine the exact details of the runoff.
The two sprinters had a time of 11.07, but after a closer look Tarmoh was unofficially timed .001 ahead of Felix on the track, but referee Bob Podkaminer overruled the time and declared it a dead heat which lead to this runoff.
There was no tie-breaking procedure in place for a tie for the final spot for the Olympic team so the choices came down to a coin toss or a runoff for the final spot to see who would represent the United States in London.
