Jeneba Tarmoh has decided to withdraw from the run-off against Allyson Felix for the final spot on the United States' women's 100-meters team for the London Olympics.

Tarmoh and Felix finished in a dead heat for third place in the 100-meters final during the U.S. Olympic track and field trials and faced several choices to determine who would take the last spot, including a coin flip.

The run-off was decided upon Sunday and scheduled for Monday afternoon, but Tarmoh sent an email to USA Track and Field on Monday morning to inform the organization of her decision.

"I, Jeneba Tarmoh, have decided to decline my 3rd place position in the 100m dash to Allyson Felix," Tarmoh wrote. "I understand that with this decision I am no longer running the 100m dash in the Olympic Games and will be an alternate for the event. As an alternate I understand that I will be asked to run if another 100m runner decides not to for personal reasons, and/or on the 4x100m relay."

Tarmoh's time of 11.068 seconds originally gave her third place over Felix by just .001 seconds, but it was later changed to a tie. Carmelita Jeter beat Tianna Madison to win the race.

"We are disappointed that Jeneba has changed her mind regarding her position on the Olympic Team," said USATF president and chairman Stephanie Hightower. "We all worked hard to reach a consensus on the tiebreaker, but we know that Allyson, Carmelita and Tianna will represent Team USA well."

Felix also qualified for the Olympics by winning the women's 200-meters on Saturday in 21.69 seconds, while Tarmoh was fifth.
