Tuhia he haere tonu mo tenei whitianga - I pouri a Rooney i te tau 2011, i pakaru i te haurua whakamutunga 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 roto i te 4 × 400 mita relay
I riro i a Martyn te tohu i te tuaono, ā, i rere ia i te 44.1 hēkona, engari kāore i taea e ia te hopu i a Deon Lendore o Trinidad, ā, i mutu i te tuawhā.
