Armstrong unaffected by claims
Paris - Lance Armstrong on Thursday gave off an air of indifference to claims that he was at the centre of the biggest doping scandal in sporting history, saying that he was concentrating on his charitable work.
"What am I doing tonight? Hanging with my family, unaffected, and thinking about this," he wrote on his Twitter account, linking to his Livestrong foundation website and a series of fund-raising events for cancer research.
The US Anti-Doping Agency on Wednesday gave its reasons into why it banned him for life in August, accusing his US Postal Service team of "the most sophisticated, professionalised and successful doping programme that sport has ever seen".
Eleven former team-mates gave evidence against Armstrong - who battled back from life-threatening cancer to win the Tour de France seven times - accusing him of taking banned substances and enforcing a doping culture within the team.
