I set my sights on making an Olympic team, not realizing how tough it was going to be.

I love track and field, but I also know the day will come when I will have to do something else.

Even at 10 or 12, I was a hot, fast little cheerleader.

Teaching kids about health and fitness is important to me. It's about being fit for life.

I maintained my edge by always being a student; you will always have something new to learn.

I was diagnosed with asthma when I was 18 during my freshman year at UCLA. I refused to accept it - and I hid it from my coaches and teammates. But ignoring my problem didn't make it go away.

When I started competing, you had to have your coach there. Now you can be coached from a home office via Skype or video. That's not the same as having them on the field with you.
