 Having more strong runners in the team (consisting of Shirley Strickland, Winsome Crisps and Verna Johnston in addition to Jackson), the Australian 4 × 100 m relay team was also a favourite for the gold, but a faulty exchange meant Jackson's chances for third gold medal were gone.The Americans, anchored by Catherine Hardy (later Lavender), won in an upset, setting a new world record time of 45.9 seconds.Later in 1952, Jackson lowered the 100 m world record time to 11.4, running this new record in a meet at Gifu, Japan on 4 October 1952.
