Mary King - British Olympic Equestrian
Mary King is a sportswoman like few others.
She's 50-years-old and still at the pinnacle of her sport.
That sport is three-day eventing.
Next year, she's hoping to collect her first Olympic gold medal - at what will be her sixth games.
But is equestrianism - as its enthusiasts insist - the toughest sport in the world?
Or is it less a test of the person - more of the horse - and a preserve of the rich?
