Is Lance Armstrong on steroids still Lance Armstrong, only a more authentic version: his truer self? In addition to taking drugs to prepare for the Tour de France, Lance also worked hard. He didn't fly through the Alps, he cycled.
When the Nobel committee finds out he was on performance-enhancing drugs, would they take the prize away?
Of course, the organizations that run the Tour de France have a list of banned drugs. To my knowledge, the Nobel committee does not.
