Although Blake was a part of Jamaica's team that qualified for the 2012 Summer Olympics, Blake never actually ran at the London Olympics. Despite not running in the women's 4 × 400 m event, Blake was accidentally awarded an Olympic bronze medal by the Jamaica Olympic Association. She did not return the medal, however. In 2013, Blake was suspended for six years after she tested positive for methylhexanamine. After her ban was lowered to years, Blake came back into competition in January 2017. Later that year, in compliance with International Association of Athletics Federations rules that mandate the return of all medals and prizes after positive testing for forbidden substances, Blake gave back her Olympic bronze medal to the Jamaica Olympic Association.
