In October 2005 the Welsh Cycling Union (WCU) selection commission decided to send a full team of six male riders to the 2006 Commonwealth Games, centered on supporting the aspirations of the National Coach Julian Winn, but also decided that Cooke would be sent as a one-person team to defend her title. In April 2016 Cooke would cite this as an example of the sexist attitudes of the sport she encountered throughout her career in an article - Welcome to the world of elite cycling where sexism is by design. In December 2005, when preparing for the 2006 Commonwealth Games, she broke a collarbone during the Manchester leg of the UCI Track World Cup; despite this, and the lack of any team support, she came third in the road race at the Games in March 2006. In her autobiography Cooke wrote "By their decision the WCU had gifted Australia, Canada, England and New Zealand my head on a plate". None of the six Welsh men completed the men's race.
