Answer
In 2016, Chad le Clos became South Africa's most decorated Olympian. At the 2016 Summer Olympics in Rio de Janeiro, he won four medals: a gold in the 200-meter butterfly, a silver in the 100-meter butterfly, and two bronzes in the 200-meter freestyle and 4x100-meter medley relay. This brought his total Olympic medal count to six, surpassing the previous record of five held by swimmer Penny Heyns.
