Cox was born in Leeds and began her sporting career as a hockey player, switching to athletics and sprinting at the age of 15. Over the next three years, her talent shone and in 2007, she won bronze at both the Manchester Open and the England Athletics Open Championships in the 60-metre sprint.
Her progress continued on the athletics track and, in 2012, Cox won bronze in the 200 metres at the BUCS Championships, held at the Olympic Stadium, part of the London 2012 official Olympic test event, before breaking the 12-second barrier in the 100 metres for the first time a year later, running 11.97 at the Northern Athletics Championships.
However, in May 2014, Cox was taken to hospital having suffered a stroke, and, after apparently returning to full fitness, further problems and extensive medical tests in September saw her diagnosed with multiple sclerosis.
Cox turned her attention to winning a place at the 2016 Paralympics in Rio and was classified as a T37 track and field athlete and a C2 track cyclist, winning gold in the C1-5 mixed gender sprint time trial at the British Cycling National Track Championships in September 2015.
A month later, Cox was competing for the Great Britain athletics team at the IPC Athletics World Championships in Doha, Qatar, where she broke the T37 100-metre world record in qualifying with a time of 13.59, before winning gold in the final.
A world champion in athletics, Cox would repeat the feat on the cycling track five months later at the 2016 UCI Para-cycling Track World Championships where she won gold in the C4 500-metre time trial in a new world record of 37.456.
That result and performance was all the more impressive as the day before the event, Cox had been reclassified from the C2 to the C4 category.
Those performances fuelled Cox’s hopes of becoming the first Great Britain para-athlete since Isabel Newstead, who competed in shooting and athletics in Seoul in 1988, to win medals in two sports at a Paralympic Games.
And those hopes moved a step closer when she was selected for the Rio team, to compete in her speciality event, the time trial, as well as the road race.
In Rio, Cox did not disappoint in either of her chosen sports as she won golds in athletics and cycling, the first Briton to do so since Barr 32 years earlier.
Cox won the 500-metre time trial in the velodrome, setting a new world record of 34.598 in the process, while enjoying even more success at the athletics stadium - gold in the T38 400 metres, silver in the T35-38 4x100-metre relay and a bronze in the T38 100 metres.
Her achievements led to Cox being selected to carry the British flag at the closing ceremony.
