The biggest way I stay motivated is to run with a group of friends. Sometimes it's hard to get going by yourself, but if you have a plan and a meeting time, you know this run will happen for sure. It's a way to have fun - while also getting in a workout. Plus it distracts from pain, helps you fight fatigue, and gives you that extra push.

Everyone sees the glory moments, but they don't see what happens behind the scenes.

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.

Before a race, I block out what's going on in the stadium. It's different for everyone. But for me, I've always been able to block it out. For a sprint race, it's important not to get distracted.

I'm an athlete who's very determined and I understand sacrifice.

I definitely think I put more pressure on myself. I can be hard on myself and super-critical and very rarely satisfied or happy. I am my biggest critic.

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.
