Like any good American sports fan, I’ve been completely transfixed by the Tour de France this year because the American defending champion is winning again. Of course, the American is Lance Armstrong, perhaps the greatest comeback figure in the history of sport (I’m not being hyperbolic either). When you read stories about Armstrong, the odds which he has overcome generally aren’t adequately described, even though that’s hard to believe when you read the descriptions. The best coverage of the Tour I’ve found is at VeloNews.
