The United States women's 4x400m relay team left very little doubt on the way to a gold medal. The U.S. women finished in 3:16:87, more than three seconds ahead of the Russians, who finished in second place with a time of 3:20:23.
With the big lead, there was very little suspense when Sanya Richards-Ross started the final leg of the race.
"By the time I got the stick," Richards-Ross said according to the Associated Press, "it was basically a victory lap."
The win capped off a tremendous 2012 Olympic games for Allyson Felix. In addition to the 4x400m relay gold, Felix also took home gold in the 4x100m relay and the women's 200m sprint.
"London is very special to me," Felix said. "It's unbelievable," she said. "I think about how I ended in Beijing, just feeling discouraged there. Four years later to have all this happen, to really accomplish every goal that I set out, is such a blessing."
While some believe Jamaica would challenge the United States in this event, they finished a distant third at 3:20:95.
"On paper, it seemed like it was going to be a great race," Richards-Ross said. "But by the time I got the stick, we had already dominated the race."
