It's totally different now, traveling to different meets and different cities and actually being able to enjoy the cities I'm in.

I didn't get nervous when I ran, but I get nervous watching other people now. I root for anybody with a USA on their chest.

People see me now and ask if I'm still running. I may look like I am, but I'm really not. People think I still run every day but I ran for 25 years and I deserve to not do anything but walk or ride the bike with my kids.

We enjoy traveling. We do it while we can.

I was diagnosed with Graves' disease, an illness of the thyroid gland. Instead of surgery, I was given radiation treatment.

Looking back, I'm so proud to have gone to five Olympics - I believe only three other Americans have achieved that. My true gold medal, though, is my daughter, Karsen, who is 18 months old. And I have a wonderful husband, Mike.
