Zoe Castle and Kate Argall have been rivals on and off the cycling track since their first meeting at the Elite training camp at the age of 19. Now, with the preparations for London 2012 underway, their last shot at Olympic gold will test them to their physical and emotional limits. Charting the highs and lows of Zoe and Kate's careers and the complex schism between their rivalry and friendship, Gold is a page-turner that's thoroughly engrossing from page one, drawing you into the girls' world of gruelling training schedules, fierce ambition and personal sacrifice. An enlightened and timely take on what it really means to be a champion.
