Olympians, Aliyah and Jasmine Abrams have already broken a record without setting a stride on the Olympic track in Tokyo, Japan.
The sisters will become the first siblings to represent Guyana at the same Olympics when the showpiece event gets underway from July 23.
For Aliyah, a 400m specialist, it will be her second Games while Jasmine who competes in the blue-riband 100m, will make her debut.
