His breakthrough to senior level came at age 18 at the 2011 South African Athletics Championships, where he won the 200m title in a 20.57 seconds. His finest moment was at the 2016 Rio Olympics when he won gold from lane eight in a time of 43.03sec, which smashed Michael Johnson’s world record which had stood for 17 years. In 2017 he suffered a potentially career-ending cruciate ligament injury playing touch rugby, but he has since bounced back and is among the world’s elite sprinters once again.
