Following a foot injury which delayed her track and field training, Cooke joined driver Nicola Minichiello in the two-woman bobsleigh as brakewoman following a trial in October 2008. Minichiello and Cooke won the gold medal in the two-woman event at the FIBT World Championships 2009 in Lake Placid, New York. The pair finished seventh at the same event in St Moritz in 2010, despite some difficulty with Cooke's prototype racing suit, which split open in the seat, seconds before the start of her bobsleigh run. At the 2010 Winter Olympics, they crashed out during the third run of the two-woman event and did not start the final run as a result.
