Lance Armstrong says the fight against cancer is the driving force in his decision to race again.
The seven-time winner of the Tour de France read a statement to reporters north of Montreal today before sharing a rain-soaked road with about 40 cyclists to promote awareness about the disease.
Armstrong says it is important for him to be able to talk about the global impact of cancer.
The 36-year-old cancer survivor told Vanity Fair this week he's 100 per cent sure he's going to compete in next summer's Tour de France.
Cyclists who joined Armstrong Friday had to raise a minimum $25,000 donation.
