Annette Edmondson was identified by the South Australian Institute of Sport as having the physical attributes of a cyclist after completing a range of measurements and physical activities at school. Edmondson began competitive cycling and never looked back, making her Olympic debut at the age of 20 at the London Olympics.
Leading into the London Olympics, Edmondson joined Melissa Hoskins and Josephine Tomic to claim team pursuit silver at the 2012 Track World Championships. With their sights set on going one better at the Olympics, the trio qualified third in the preliminary round in London. They were then beaten into the gold medal ride by a United States team just 0.082 seconds quicker than the Aussies, sending Edmondson and company into the bronze medal race against Canada. Further heartbreak followed as the team in green and gold was edged out of the bronze medal spot by just 0.181 seconds.
Determined to improve on fourth place in the team pursuit, Edmondson backed up for the gruelling six leg omnium event that made its debut at the 2012 Games. The youngster’s consistency saw her finish in the top four in five of the six events and secure the bronze medal behind Great Britain’s Laura Trott and Sarah Hammer of the USA.
Annette's younger brother Alex was also selected for the London Olympics in the Team Pursuit but he did not get a ride in the experience Australian silver medal winning team.
