Running just makes me happy. I love the freedom of running. I ran until I was seven and a half months pregnant with each of my babies. When I gave birth to my first son, my doctor said I couldn't run for six weeks. I was sneaking back out after eight days.

I gave birth to my first son in April 1986. I thought it would be a good goal to get back in shape after having a baby if I ran the New York City Marathon. I ran in it November 1986. I had just shot the 'Sports Illustrated' swimsuit issue, so I was in great shape.

I love babies. I love being pregnant and I loved giving birth.

In the first half, we had seven or eight shots go in and out.

I found out I was pregnant seven days after my wedding. I was on honeymoon with my family.

When I was 20, my husband at the time looked at me said, 'You're fat; go run.' There weren't a lot of tools at the end of the '70s to lose weight. It took me a while to realize what kind of exercise would make me happy and I would look forward to doing. And running became it.
