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

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

When I'm running fast, I don't feel anything, it's effortless, it's like my feet don't even touch the ground, it's like I'm flying.

Now, I talk to athletes who answer questions with a 'yeah'. I realize I used to do that. Or they answer very quickly and you stand there trying to come up with another question to ask. I've seen both sides and it's been very educational.

I've noticed that since I've been pregnant I see babies everywhere. I love talking to them. I never used to really like kids that much. I guess it comes out of you naturally.

I have a nice family and I'm well rounded.

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.
