During the countdown to the 60th BBC Sports Personality of the Year award on Sunday 15 December, we will be looking at each of the 10 shortlisted contenders.
Sir Ben Ainslie looks back on what has been an "amazing and difficult" 2013.
Ainslie masterminded Team USA's incredible 9-8 comeback win over Team New Zealand in the America's Cup.
But this victory was tempered by the fact he lost close friend and fellow Olympic gold medallist Andrew Simpson, who died while training for the America's Cup.
Public voting for the 2013 Sports Personality will take place by phone and online during a live show on Sunday, 15 December from the First Direct Arena in Leeds.
