Jones, wearing chrome-plated shoes so shiny they looked like mirrors, went sleeveless on a cool night on which wind swirled around the soldout 110,000-seat Olympic Stadium.

After a false start by Ekaterini Thanou of Greece, Jones made up an early deficit to Jamaica’s Tanya Lawrence and sped past the field to win by a comfortable margin. Thanou won the silver medal in 11.12 seconds and Lawrence was third in 11.18.

The only bigger winning margin in an Olympic 100-meter final, either men’s or women’s, was Marjorie Jackson’s win by .38 over Daphne Hasenjager in 1952.

Merlene Ottey of Jamaica, who has won seven Olympic medals, finished fourth — a hundredth of a second behind Lawrence. Ottey, 40, recently returned from a one-year drug suspension.

Jones’ victory was the first step in what she has made a quest for five gold medals. Only one track athlete, the “Flying Finn” Paavo Nurmi, has won that many in one Olympics. He did it in Paris 76 years ago.

“It’s nice to have the first one done. I don’t know if it’s going to be harder or easier [from now on],” she said. “I’ve seen a lot of Olympic Games, I’ve seen a lot of people cross the [finish] line and I was thinking about it.
