Kirsty Young's castaway is the Olympian and rower, Dame Katherine Grainger. A six-time rowing World Champion across a variety of classes, her silver medal at Rio in 2016 made her the most successful female British Olympic athlete ever, having won medals in five consecutive games.

Born in Glasgow in 1975, her parents were teachers. At school she earned a black belt in karate, and it wasn't until she went to Edinburgh University that her passion for rowing was truly ignited. Winning silver medals at the Sydney, Athens and Beijing Olympics, Katherine finally ceased to be the sport's eternal bridesmaid when, with her partner Anna Watkins, she won gold in the Double Sculls at the 2012 London Olympics. After two years away from the sport, Katherine returned in 2014, to win her fourth silver and fifth overall Olympic medal at the 2016 Rio Olympics with her new partner, Vicky Thornley.

Alongside her sporting achievements, she gained an Honours degree in Law from Edinburgh, a Masters in Medical Law from Glasgow University and was awarded a PhD in Homicide Sentencing from King's College London in 2013. She was made the fourth Chancellor of Oxford Brookes University in 2015 and became a Dame in the 2017 New Year Honours.
