I can feel the wind go by when I run. It feels good. It feels fast.

I always want to be the best and if I can't, I don't want to run.

I believe in women. I believe in myself. I believe in my body.

I am thrilled to be 31, still running and having my daughter watch me even if it is on TV.

I was single-minded and I had tunnel vision. Now it's time for a change.

Before me, sprinters retired at 23 or 24. I run because I still like it, I can make a living, and I feel I was born to do it. And because people tell me I can't do it.

Whatever muscles I have are the product of my own hard work and nothing else.
