Cape Town - South African Olympic champion Chad le Clos has parted ways with coach Graham Hill after the pair spent 14 years working together.
Le Clos, now 24, announced the news on his official website on Thursday.
"Graham Hill has done a great job as my coach for 14 years. We have achieved a lot together at every level of the sport: The Olympics, The World Championships, The Commonwealth Games and The FINA World Cups," Le Clos said.
"However, having considered everything, I have decided to end our agreement and will now start looking to find a new structure for 2017.
"For the rest of the 2016 season, I will work by myself. Every athlete has to take responsibility for his or her own career and I feel ready to try a different approach.
"I would like though to thank Graham for all his hard work, his advice and his friendship. I’ve been fortunate to have one of the best swimming coaches in the world living so close to my family home here in Durban. It has been an incredible journey together and he and his family will always remain good friends."
Le Clos won two silvers at the 2016 Rio Olympics in the 200m freestyle and 100m butterfly, while he won a gold and a silver at the 2012 London Olympics in the 200m and 100m butterfly respectively, making him the most decorated South African Olympian of all time.
