Cycling legend Lance Armstrong today confirmed his new Radio Shack team will make their road racing debut in Australia's Tour Down Under. The seven-time Tour de France winner revealed he was keen to take part in the event which would also help boost awareness of his cancer work. ``We are going to go back to South Australia with the Tour Down Under, based on the fact that it's a great race, great community,'' the Texan said. Armstrong, who survived testicular cancer and this year came out of retirement to finish third in the Tour de France, announced the formation of Team Radio Shack in July. At the final day of Armstrong's global cancer summit in Dublin, South Australia Premier Mike Rann said he was thrilled to have the cyclist return. The 2010 Tour Down Under takes place from January 17 to 24.
