I exercise everyday. I swim, I bike, I run and I go to the gym.

What makes a great endurance athlete is the ability to absorb potential embarrassment, and to suffer without complaint.

Anything is possible, but you have to believe and you have to fight.

I think I bit off more than I could chew, I thought the marathon would be easier. For the level of condition that I have now, that was without a doubt the hardest physical thing I have ever done.

Me and running don’t always see eye to eye. Some days it hurts more than others. But it doesn’t mean I don’t do it. I deal with it and I keep running because not everything that is good for you, always feels good for you.

You know, once I was thinking of quitting when I was diagnosed with brain, lung and testicular cancer all at the same time. But with the love and support of my friends and family, I got back on the bike and won the Tour de France five times in a row. But I'm sure you have a good reason to quit.
