Switzerland's Fabian Cancellara has revealed 2016 will be his last as a professional cyclist.
Cancellara - a former world and Olympic time-trial champion - made the announcement at a cycling awards ceremony in Zurich on Wednesday.
The 34-year-old, who turned professional in 2001, added that he will not compete at the Olympic Games in Rio de Janeiro next year.
"Next year is my last year," Cancellara said in an interview with SRF. "The timing was just right.
"Cycling is not my life, but only a part of my life.
"The Rio Games are not on my programme."
Cancellara, who won gold in the time-trial at the 2008 Beijing Games, is a three-time winner of both the Tour of Flanders and Paris-Roubaix.
The Trek Factory Racing rider is also an eight-time individual stage winner at the Tour de France, his most recent victory coming in 2012.
Cancellara wore the yellow jersey this year up until stage three, when he fractured two vertebrae in a shocking crash.
He later withdrew from the Vuelta a Espana in August and the UCI Road World Championships a month later due to illness.
