As a kid, I was a little fat. In college, I was less active, and I started blowing up. It got out of control when I went to law school. At the age of 30, I weighed 414 pounds. I was always tired. I have a family history of heart disease, and I was scared. I also wanted to look better. So a few weeks after my birthday, in the spring of 2006, I started to lose weight.    
Walking was all I could do at first. I started by walking to a subway stop a few blocks away instead of the one closest to my apartment. I gradually increased the distance. A year later, I started to run. At first I could run for only two minutes, but I kept on.    
I made a difference. I was losing nine or ten pounds a month, and I had a lot more energy. I started to think about the New York City Marathon, which goes right past my apartment building. For years, I thought I could never do that. But now I realized that maybe I could…   
By my 33rd birthday, in the spring of 2009, I was down to 180 pounds. That summer, I started formally training for the marathon. And on the morning of November 1, I stood on the Verrazano Bridge in Staten Island with more than 40,000 other runners, waiting for the event to start.
When we started moving, it was an amazing feeling to have people cheering me on, handing me cups of water. In Harlem, my mom and brother stood on a street corner, waving. And then I crossed the finishing line in Central Park, and somebody put a medal around my neck. I was in tears from being so happy.
