Over the course of her career, she has won eight world titles and 81 PSA championships and, at one point, was the longest reigning world no. 1 in squash history for 109 consecutive months between 2006 and 2015.
Outside the PSA competition, Nicol has also enjoyed success at the World Games, Commonweatlh Games and Asian Games.
