Twenty years ago, rower Greg Searle won Gold in the Coxed Pair alongside his brother Jonny, at the Barcelona Olympic Games. At the age of 20, he received an MBE, and by the time he had reached his mid-thirties, his glorious career as an international athlete was over. Or was it?

If Not Now, When? is a book about obsession; about the drive to be the best you can be, whatever your age. In April 2010, and almost two decades older than the rest of the British rowing squad, Greg made the decision to come out of retirement and go for gold again at the London 2012 Olympics. His journey gets to the very heart of what it means to compete; teamwork and loyalty, the struggle to deal with disappointment and the will to win.

In the 2012 final, Greg won bronze as part of the men's eight and sealed his status as Olympic legend.
