Sydney - Australia's Cadel Evans says he wants to ride in at least two more Tour de France races before he considers retiring from the event.
Evans, 34, last July became Australia's maiden winner of the world's premier stage race and the oldest Tour de France winner for 88 years.
He said he wanted to continue riding the Tour for as long as he remained competitive.
"Two more tours, two more good tours at least," Evans told reporters in Darwin late Tuesday.
He said his team was looking closely at how his body was ageing.
"I keep improving and I am not showing signs of ageing in a physical way," he said.
"As long I can be in the Tour to win it and go for the win, I want to keep going."
Evans has ruled out competing at Australia's Tour Down Under in Adelaide in January as he aims for world and Olympic glory next year as well as defending his coveted yellow jersey.
The Olympic men's road race will be held early August in London while the world championships road race is in Limburg, the Netherlands, in late September.
