Whakakī i te rerenga e whai ake nei: I pouri a Rooney i te tau 2011, i hinga ia i nga whiringa toa o te 400 mita i te Whakataetae o te Ao i Daegu me te whakaoti i te tuawaru hei waahanga o te roopu o Ingarangi i te 4 × 400 m relay. I te tau 2012 i tiimata pai a Martyn, e rere ana i te 44.92s i te Paenga-whawha i te Mt. SAC Relays i Walnut, California, tōna wā tere rawa mai i te tau 2008. Kaore i taea e Rooney te pupuri i taua ahua ki te haere ki tana Olympics kaainga, a ka whakakorea ia i te haurua whakamutunga o te 400 mita, e rere ana i te 45.31s. I te
4 × 400 metres relay final Martyn i riro i te baton i te tuaono o nga waahi ka rere i te 44.1 tuarua o te waewae pungawerewere, engari kaore i taea e Deon Lendore o Trinidad, a ka mutu te tuawha.
