(CNN) -- With three places up for grabs on the U.S. Olympic track team, two women tied for third place in the women's 100 meters over the weekend -- crossing the line at exactly the same time -- which means the coveted Olympic spot could be decided by a coin toss. Sprinters Allyson Felix and Jeneba Tarmoh threw their bodies across the finish line so evenly matched that cameras recording 3,000 frames a second couldn't tell who beat whom. Both runners recorded precisely the same finishing time, down to thousandths of a second: 11.068 seconds. Two women beat Felix and Tarmoh: Carmelita Jeter and Tianna Madison. Their first and second place finishes on Saturday give them the chance to represent the United States at the Olympics in London this summer.

Olympic officials are giving them the choice of a rematch or a coin toss

There doesn't appear to be any precedent in U.S. Olympic trials for a dead heat
And if both athletes refuse to declare a preference, officials will flip a coin -- a @placeholder quarter to be exact.
