There is no pill, no drug, that can do for you what one hour of exercise can.

I know it is possible to win the Tour without taking anything.

The key is being able to endure psychologically. When you're not riding well, you think, why suffer? Why push yourself for four or five hours? The mountains are the pinnacle of suffering

Testing, we will never do enough of it.

I rode in a nine-day charity ride recently, averaged 43km a day and still finished in the lead group. I'm 38, not quite finished yet.

The problem with being a Tour de France winner is you always have that feeling of disappointment if you don't win again. That's the curse of the Tour de France.

I'm more optimistic about cycling right now than I've ever been.
