Sun Yang, the only swimmer to win Olympic 200m and 1500m freestyle titles, said he wants to end his career at the 2020 Tokyo Olympics, according China’s Xinhua News Agency.
“I didn’t skip training for a single day [after Rio], and will keep training hard for the Tokyo Games, and I hope to win more gold medals there for a perfect ending of my swimming career,” Sun said, according to the report.
Sun, 24, won 200m free gold in Rio after taking the 400m free and 1500m free titles in 2012.
He is one of the most controversial swimmers in the world, having served a doping ban and angered other swimmers and his federation with his conduct.
