South African Paralympics swimming legend Natalie du Toit has revealed that she is not sure what her future holds after her retirement from competition.

Du Toit, who won silver in her final swimming event earlier this evening, said that she wants to work and study but is not sure what she will enjoy doing.

"I've gone out there and tried my best in every race," Du Toit said. "It was my last race ever so I'm a bit relieved.

"I have no idea what's next. It's about starting another life and enjoying what you do.

"I want to study, I want to start working [but] I don't know what I'll enjoy, I just want to go out there and see what happens."

Du Toit has 13 gold medals since first competing at the Paralympics in 2004.
