Life to me is a series of false limits and my challenge as an athlete is to explore those limits

I'm not willing to put a percentage on the chances but I will no longer rule it out.

We all want to be forgiven. There's a lot of really, really bad people who want to be forgiven but will never be forgiven, and I might be in that camp.

I don't think anybody else from my generation had federal agents standing at their door with a badge and a gun, saying: 'You are going to answer my questions'.

My cocktail, so to speak, was only EPO, but not a lot, transfusions and testosterone.

The unwillingness to accept anything short of victory, that underlying fury, is the fundamental building block of my bottomless motivation to succeed. It is my credo in all that I do in life from battling cancer to bicycle racing.

Two things scare me. The first is getting hurt. But that's not nearly as scary as the second, which is losing.
