Try to think of working out and healthy eating as a lifestyle. Rather than go on a diet or try a crazy exercise routine, try making them something you do every day.

I focused solely on the sprints, dedicated my time there, got in the weight room, just really did everything I could to make sure I would be in the best position to run for gold.

There was a race that I was running in Mexico City and I was the only high school athlete running against grown women. It was a professional race, but I ended up winning. That was kind of a turning point for me where I felt like, "Okay, I'm pretty good at this and there's a possibility for this to be a career for me." That was a defining moment for me.

My faith inspires me so much. It is the very reason that I run. I feel that my running is completely a gift from God and it is my responsibility to use it to glorify him.

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

I think I'm a person who is proud of my [Christian] faith and where I come from.

It was not until the end of my freshman year in high school that I thought I could really have a future in track and field. I definitely did not think I could make it to the Olympics back then, though; I was just focused on making it to the state finals!
