Three-time Australian world time-trial champion Michael Rogers has announced his immediate retirement from cycling due to a heart condition.
The four-time Olympian, who won a bronze medal in the road time-trial at the Athens 2004 Olympic Games, has not competed since February when the issue forced him to pull out of the Dubai Tour.
"All great dreams eventually come to an end, and today it's time to conclude mine by announcing my retirement from racing," Rogers confirmed via an online message.
"Recent cardiac examinations have identified occurrences of heart arrhythmia which have never been detected beforehand.
"This latest diagnosis, added to the congenital heart condition I was diagnosed with in 2001, means that my competitive career must end."
Rogers also highlighted his disappointment of missing out on a 13th Tour de France and his chance to represent Australia at the Rio 2016 Olympics.
Aside from his three world championships, his other career highlights include a purple patch in 2014 in which he won two stages at the Giro d'Italia and another at the Tour de France.
