She is the National record holder in the event, improving her own record to 1:58.67 on August 9, 2012 in the semi-final round of the Women's 800m event at the 2012 Summer Olympics. It was a 0.01 seconds improvement on her previous record. Two days later she finished seventh (subsequently upgraded to fifth as a result of the doping disqualifications of Russian athletes Elena Arzhakova and Mariya Savinova) in the 2012 Olympic final. Less than a month later she took the record down yet again to 1:56.59.
