Coming up on this weekend's edition of World Olympic Dreams on BBC News:
Matthew Pinsent travels to Rio - host city of the 2016 Olympics - to meet young athletes hoping to compete there, and at London 2012. He meets a young man whose father's death at the hands of drug lords spurred him to take up boxing.
Elsewhere, India's five-time world women's boxing champion MC Mary Kom discusses the difficulty of targetting gold at London 2012 whilst raising two children.
And our reporter heads to the village in Pakistan that has produced no fewer than 57 international hockey players.
