Cycling great Lance Armstrong is coming out of retirement to try to win an eighth Tour de France in 2009.
The American, who will be 37 next week, recovered from cancer and claimed victory in the Tour a record seven times before retiring in 2005.
He says after talking with his children, family and closest friends he's decided to return to professional cycling in order to raise awareness of the global cancer burden.
Armstrong beat testicular cancer before embarking on his remarkable run of Tour de France victories.
Since his retirement in 2005, he has run twice in the New York City Marathon and also the Boston Marathon.
Talk of his comeback was fuelled when the US anti-doping agency confirmed he had reinstated himself in its out-of-competition testing pool.
Armstrong's spokesman Mark Higgins says it's undecided which team he will ride for and in what other races.
