There are moments that aren't great. And I think it's amazing for people to be able to have some insight, to be able to see the support system and what really happens.

I am a big believer in visualization. I run through my races mentally so that I feel even more prepared.

What's really heavy on my heart is fighting physical inactivity.

I feel like my name completely does not belong on that list [of great athlets], but I'm completely grateful for everything that they [Jackie Joyner-Kersee, Florence Griffith-Joyner and even Wilma Rudolph] have done.

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'm always nervous. If I wasn't nervous, it would be weird. I get the same feeling at all the big races. It's part of the routine, and I accept it. It means I'm there and I'm ready.

As a female athlete, you're always fighting to be on a level playing field with your male counterparts. But I believe the Olympics is great for young girls; they get to be exposed to so many different sports and to these really strong women. It's an opportunity to showcase what we do, which is something that men get the opportunity to do on a pretty regular basis.
