I am so proud and inspired by my friend, Olympic Gold Medalist, former team-mate and former nemesis, Natalie Cook, who has defied the odds and qualified for the London Olympic Games ( london2012.com ) Рher 5th, a record for an Australian women at the summer games. What kind of motivation does it take to make it to one Olympics, let alone five?   What drives one to go the extra distance?
