Other Tours for Armstrong?

Speaking at a motivational event in Mexico City on Wednesday, Lance Armstrong suggested to the audience that if he were to rejoin the professional peloton, the Giro d'Italia or Vuelta a España could be possibilities - adding "there are a lot of reasons" not to return to the Tour de France.

"There are a lot of reasons not to do [another Tour de France]; the fact that I would open myself up for even more questioning, scrutiny, potential sabotage and potential unfair accusations," Armstrong was reported on Reuters to have said. "That's not appealing. But at the same time I think I'm still in my prime, I think I can still ride at a high level."

Added the 33 year-old, "The Tour de France is not the only bike race in the world, but it is the biggest, so the possibility could still exist to do a Tour of Italy, a Tour of Spain."

However, the seven-time Tour winner said there were also plenty of reasons not to return to his former profession: "My kids would be livid, my fiancée would be livid and my [cancer] foundation would not be happy about it," he said. "There are lots of reasons not to do it. In the meantime, I'll just ride my bike every day and think about it."
