AUSTIN, Texas (AP) - TeamRadioShack, Lance Armstrong's new cycling team, will debut at the 2010 Tour Down Under in Australia.
Armstrong, who finished third in the Tour de France in July while racing for Astana, made the announcement Wednesday on his Twitter page.
Armstrong won the Tour de France a record seven times from 1999-2005 before retiring. He announced his return to the sport in 2009.
The Tour Down Under runs Jan. 17-24 in Adelaide and other communities around South Australia.
Adelaide state premier Mike Rann said he met with Armstrong in Ireland on Wednesday to complete arrangements for the American star to return in 2010.
"He really enjoyed his time in South Australia and has told me how much he appreciated the massive support he received," Rann said in a statement.
Armstrong's entry in this year's Tour Down Under helped attract an estimated 750,000 spectators which the government said injected $30 million into the region's economy.
