Australian gold medal-winning swimmer Mack Horton has announced his shock retirement.
Just six months out from the Paris Games, the 27-year-old has decided to step away from the pool.
Mr Horton announced his decision on Sunday with a video tribute on social media.
He won the 400-meter freestyle at the 2016 Rio Olympics and the 2018 Commonwealth Games.
Along with his gold medals, Horton is best known for his refusal to stand on the podium with China’s Sun Yang, over allegations of doping.
