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 love the relays. Track is such an individual sport, so it's fun to do something together.

The most important lesson that I have learned is to trust God in every circumstance. Lots of times we go through different trials and following God's plan seems like it doesn't make any sense at all. God is always in control and he will never leave us.

If I wasn't active and involved in different sports and just moving around, I wouldn't have even known that I had the potential to become an Olympian.

I always look back to my first Olympic medal in 2004 in Athens. I was very new to the sport, and it was my first big win at the Olympics.

My faith is the reason I run - it calms my heart and makes everything feel like a lift. My speed is definitely a gift from Him, and I run for His glory. Whatever I do, He allows me to do it.

Most people don't think about plyometrics when they think about powerful strength. But I do lots of them to build mine.
