Jessica Zelinka did double duty in her second Olympic Games appearance when she finished seventh in both the heptathlon and 100m hurdles at London 2012. That came four years after she had achieved the best-ever result by a Canadian in the Olympic heptathlon, when she finished fifth at Beijing 2008.
Zelinka had qualified in both events for London 2012 with an astounding performance at the Canadian championships. She shattered her own national record in the heptathlon with a score of 6599 points and also won the highly anticipated 100m hurdles final. Zelinka has been an elite international competitor for a number of years, winning gold at the 2007 Pan American Games and silver at the 2010 Commonwealth Games.
