I never let track define me. That's something that's really important to me.

I spend around two and half hours on the track every day running and another 2 hours in the weight room lifting weights with my strength coach.

I try to think about my goals. I think about my competitors-I know they're working hard, and if they are, I have to work hard too. I have to be one step ahead of them.

Try to think of working out and healthy eating as a lifestyle. Rather than go on a diet or try a crazy exercise routine, try making them something you do every day.

I know that they [Jackie Joyner-Kersee, Florence Griffith-Joyner and even Wilma Rudolph] have paved the way and they have been a source of inspiration.

The pressure is hard. You get - the world is only watching every four years, and I think lots of people feel like they have to win in that time frame.

I have learned that track doesn't define me. My faith defines me. I'm running because I have been blessed with a gift.
