From OpenwaterpediaRandy Bennett. For the year of 2010, Cochrane was named the Canadian male swimmer of the year at the 2010 Big Splash Awards Gala in Toronto.
He also competed in the RCP Tiburon Mile and announced his retirement on 1 April 2013 from competitive swimming to join Canada's national bobsleighing team in a quest to represent Canada at the 2014 Sochi Winter Olympic Games. The April Fool's joke was exposed when Cochrane continued to win at the Swimming Canada's World Championship Trials during the first week of April 2013.
Cochrane competed in the 2008 Beijing Olympics in the 400m freestyle where he finished ninth in the heats with a Canadian record time of 3:44.85 and failed to qualify for the final. Cochrane also competed in the 1500 m freestyle where he briefly held the Olympic record after swimming a time of 14:40.84 in the heats. This record was soon broken by previous record holder Grant Hackett, who swam a time of 14:38.92.He qualified in second position for the final, and won the bronze medal on August 17. It was the first Olympic medal for a Canadian swimmer since the 2000 Olympics. It was the first medal for Canada in the 1500m freestyle in 88 years.
At the 2010 Commonwealth Games in Delhi, India Cochrane won Canada's first gold medal of those games in the 400m freestyle during the first day of competition. Cochrane also became the first Canadian man in 72 years to win gold in the 400m freestyle at the Commonwealth Games. He then went on to win another gold medal at those games, this time in the 1500m freestyle.
Cochrane next competed at the 2011 World Swimming Championships where he opened up with a fifth place finish in the 400m. Next up was one of his medal hopeful events in the 800 m freestyle where he lowered his Canadian record to 7:41:86. However this was only good enough for second, as despite staying close to the hometown favorite of Shanghai, Sun Yang ultimately took the gold for China.
He next competed in the 1,500m in Shanghai where he again finished second behind Sun who swam to a world record time.
The 2012 Olympics began with Cochrane competing on the first day of competition in the 400m freestyle. There Cochrane won his heat and qualified in the last spot for the final. However after Park Tae-Hwan's disqualification was overturned, Cochrane was pushed out of the final and missed swimming in it by 1/100th of a second. He next entered his signature event the 1500m where he qualified through the heats in third place. In the final Cochrane managed to outswim Oussama Mellouli for the silver medal and achieved it in a personal best time. With his second medal at his second consecutive Olympics, according to media such as the CBC this cemented Cochrane as Canada's pillar athlete to build its swimming team around for the future as he declared that he would try and swim for Canada at the 2016 Summer Olympics in Rio de Janeiro. But a recent press release on 1 April can turned that hope from Swimming Canada to Bobsleigh Canada.
