Armstrong makes Australian return hint

(CNN) -- Seven-times Tour de France winner Lance Armstrong could make his cycling comeback at the Tour Down Under in January.

Armstrong, who turned 37 on Thursday, announced he was coming out of retirement earlier this month in a bid to not only to become the oldest Tour winner, but also to raise awareness about cancer.

And in an e-mail to the Sydney Morning Herald, the American indicated he might use the season-opening Tour Down Under as a starting point for his campaign.

"The most important issue is taking the global epidemic of cancer really to a much bigger stage," said Armstrong, who previously fought a battle with testicular cancer.

"The best way to do that is to race the bike all over the world. So you race in Australia, South Africa, South America, Europe, America -- that is the first priority," added the Texan.

When Armstrong was asked if he had singled out the Australian event as his return race, the Texan replied: "I have no clear answer for you. My aim is to race all over, where there are willing and supportive governments with regards to enacting cancer policy. Australia seems liked an obvious choice, but I have no plans yet."

Tour Down Under organiser Mike Turtur has denied reports that Armstrong has already committed himself to the race, which runs from January 20 to 25.

"We have had no official word from the Armstrong camp. We, along with everyone else, are waiting for his announcement next Wednesday," Turtur said.

"We have contacted his management asking what their thoughts are. Their response was that they are going to discuss internally their program and will get back to us as soon as possible. "There has been nothing more than that. There has been no commitment."
