My mom is great and I make sure that we pray together before every race. She helps me put everything in perspective and remind me of the real reason I run.

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

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 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.
