I started running track when I was 13 years old, as a freshman in high school. I ran the 400 meters, which is a very tough race and a full sprint.

Growing up, my parents were healthy eaters and starting to run and compete when I was 13, I knew the need to focus on what you need to eat. I remember going to grocery store myself and picking up fresh fruit and knowing early on the right foods to fuel my body.

I grew up in San Antonio, Texas, and went to a big high school called Douglas McArthur where there was a lot of track and a lot of football. It was a bit like 'Friday Night Lights.' I used to spend a lot of time at the track.

I dont love the phrase balancing work and family. It sets up this idea of scales of justice with work on one side and family on the other side.

I really enjoy making sure the kids get a healthy dinner, a good bath and several books... I really like to try and end the day with some quality time with my kids. If not, I feel guilty.

More people more accepting of civil unions and gay marriage, which our pollster said was the most significant change they've seen on any social issue. So, this country is changing in a way.

You face challenges in your personal life and in your professional life. I continue to be relentlessly optimistic and not focus on the negative.
