Book excerpt: Kelly Holmes made history when she brought home double gold in the 2004 Olympics, becoming a national hero. She won Sports Personality of the Year, was given a Damehood, fully backed London's successful 2012 Olympic bid and became a superstar on the red carpet as well as a much acclaimed and consulted professional in the sporting world. Now in her staggeringly honest updated autobiography she reveals the times she fought back tears to battle against injury and win gold, plus the emotional decision she made to retire from athletics. Including details of her unsettled childhood, trials in the army and a struggle with self harm, Kelly's amazing determination carries through to make this inspirational and powerful autobiography a tale of triumph over adversity and a model for readers of all ages and backgrounds.
