Allyson Felix will run in the 100 and 200 metres at the London Olympics after Jeneba Tarmoh backed out of a planned run-off for the last 100m berth on Monday, USA Track and Field announced.
Tarmoh sent an email to officials on Monday morning saying that she was withdrawing from the run-off, which had been scheduled for Monday afternoon to settle a deadlock after Tarmoh and Felix finished in a dead heat for third place, and the last Olympic spot on offer, in the women's 100 nine days before.
"I Jeneba Tarmoh have decided to decline my 3rd place position in the 100m dash to Allyson Felix," Tarmoh wrote in an email forwarded from Tarmoh's agent, Kimberly Holland, to USA Track and Field president Stephanie Hightower.
"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."
Felix and Tarmoh are training partners under coach Bob Kersee, who was adamant that he did not want to have a run-off before Tuesday because of the potential injury risk it posed to both women after each ran a heat of the 200 on Thursday, Friday and Saturday.
Felix, the 2004 and 2008 Olympic 200m runner-up, easily booked her berth in the 200 at London on Saturday by winning the final in 21.69, the sixth-fastest time in event history and the best time in the world since 1998.
Tarmoh and Felix shared third after a photo finish proved inconclusive and were given identical timings of 11.068 seconds in the race.
