DJ sets hurdler Dai Greene on track to Olympic gold

World 400m hurdles champion Dai Greene is working with music producer Redlight and sports psychologist Dr Costas Karageorghis to create a track to inspire him to Olympic gold.

Greene says he hopes the innovative idea will give him the edge in a tightly competitive event, while Dr Karageorghis says he aims to condition the Welshman into associating the music with "peak performance".
