At the 1952 Summer Olympics, Cripps was unlucky to come away without a medal, in the 100 metres she won her first round heat in 12 seconds, then came third in her second round race, luckily the first three from each heat qualified for the semi-finals, in her semi-final she again ran in a time of 12 seconds and finished behind fellow Australian, Marjorie Jackson who ran an equalling World Record time of 11.5 seconds, in the final she ran her best time of 11.9 seconds but only managed to finish in fourth place. A couple of days later she competed in the 200 metres, in her first round heat she finished second and qualified for the next round where again she finished second, and in the final she yet again finished in fourth place. Cripps last event was the 4 x 100 metres relay and with her team mates Marjorie Jackson, Verna Johnston and Shirley Strickland they broke the World Record in their heat running a time off 46.1 seconds, in the final they were ahead until when Cripps (on the third leg) passed the baton to Jackson, somehow Cripps knee hit the baton in Jackson's hand and it fell to the floor, even though it bounced up and Jackson caught it time had been lost and they ended up finishing fifth and to make things worse the United States quartet broke the World Record.
