(CNN) -- Two sprinters who tied for the same spot on the U.S. Olympic team will duke it out on the track Monday to determine who will get to run the 100-meter race in London.
At the U.S. Olympic track and field trials last weekend, Allyson Felix and Jeneba Tarmoh both hurled their torsos over the finish line at precisely the same time -- 11.068 seconds.
Even cameras recording 3,000 frames a second couldn't tell who beat whom.
The two women tied for third place, behind Carmelita Jeter and Tianna Madison. The top three finishers get to go to the Olympics.
Monday's run-off between Felix and Tarmoh will take place at 5 p.m. (8 p.m. ET) at Hayward Field in Eugene, Oregon, according to USA Track & Field.
"The tie-breaking decision came Sunday afternoon after a meeting with the athletes, their representatives, coach and USATF officials," the organization said.
By having a run-off, the women avoid leaving their fate to a coin toss, which track officials said was an option.
Alternatively, one woman could have volunteered to concede -- but that obviously didn't happen.
There appears to be no precedent for a dead heat at U.S. Olympic track and field trials, prompting the U.S. Olympic Committee to announce new rules last weekend.
Felix already has a ticket to London, winning the women's 200-meter race on Saturday. Tarmoh finished fifth in that race.
