Martyn Joseph Rooney is an English sprinter who specialises in the 400 metres event. He reached the 400160m final at the 2008 Summer Olympics and also finished fourth in the 4400 metres relay. A mainstay on the anchor leg of the Great Britainx 400 metre relay team, at the 2009 World Championships in Athletics he won a silver medal with the Great Britain relay team, and in the 2015 edition, won bronze. His personal best time is 44.45160seconds.
Born and raised in Thornton Heath, London, the second of four children born to Marie and Liam Rooney Sr., Irish immigrants from Sligo and Westmeath, respectively, Rooney started running for Croydon Harriers just before starting his secondary school, The John Fisher School. He attended St James the Great Primary School, Thornton Heath where his mum teaches. As a result, he became an avid Crystal Palace F.C. fan. Initially training and competing at the middle distances 800 metres and 1500 metres and doing cross country throughout the winter, Rooneys talent for the one lap sprint was discovered by coincidence when he stood in to make up points at a London fixture.
