The fastest time to run a 4 x 100 metres relay is 1 min 4.19 sec and was achieved by The Pinkettes Brittney McGlone, Jessica Penney, Laura Juliff and Casey Case (all Australia) at the Venus Embrace Closest Stiletto Relay event held in Sydney, NSW, Australia, on 28 September 2010.
A custom-made 7cm high and 1.5cm wide device was used to measure the heels of each participant. Only heels that were taller and thinner than this were approved for the event.
The course was measured by experienced track-and-field judges, who also assisted in the monitoring of baton changes and timing.
The event raised over $100,000 for the Breast Cancer Foundation.
