Katherine Grainger was Great Britain's finest woman rower, but there was one gigantic itch that needed to be scratched. On 3 August 2012, on the water at Eton Dorney, she - and Anna Watkins - rubbed away and London 2012 Olympic Games women's Double Sculls gold medals were theirs. Three times an Olympic silver medallist, her career was complete and, at the age of 36, she could retire an Olympic champion, to go with her six World Championships and eight World Cup gold medals. Kath's story is an remarkable one - proof that nice people can be winners and dedication and hard work pays off. Incredibly bright, Grainger combined her athletic career with her education and she has degrees from Glasgow and Edinburgh Univeristies and a PhD from London, in subjects as diverse as law, philosophy and homicide. No wonder she is so much in demand as a much and motivational speaker. Katherine Grainger: The Autobiography tells the inspirational story of one of Britain's golden girls from London 2012.
