[3] Morris was named to the team for Great Britain at the 2008 Summer Paralympics, where she competed in the road race and time trial in the HC A/B/C disability category for athletes who use a handcycle.

[5][7][8] At the 2010 UCI Para-cycling Road World Championships held in Baie-Comeau, Canada, Morris won two gold medals.

[11][12] In July 2012 her participation at the Games was placed in doubt after she was hit by a car during a time trial near her home in Farnham, Surrey.

[14][15] In addition to her physical injuries Morris' handcycle was damaged in the crash, meaning she had to use her competition bike for training and order a new one for use in the Paralympics.

[18] However Morris was forced to give up the sport after undergoing two shoulder operations after the Games, after which she spent almost a year in hospital recovering.
