The United States won the women's 4x100-meter relay at the 2012 Summer Olympics in London on Friday, and in the process smashed the world record with a time of 40.82 seconds. The foursome of Tianna Madison, Allyson Felix, Bianca Knight and Carmelita Jeter became the first to collectively run under 41 seconds, breaking a 27-year-old record held by East Germany.
After the race, Jeter said she knew from the outset that the relay team could set a world record. Madison did too, but even she was shocked by just how dominant the performance was.
"I knew that the Olympic record was coming down," she said. "I just knew that if we had clean baton passes that we would definitely challenge the world record. Smash it like we did? I had no idea. But I knew it was in us."
The United States beat a favored Jamaican squad by almost six-tenths of a second for the win. Ukraine took the bronze, setting a national record with a time of 42.04 seconds. Felix has now won two gold medals at the London games. Jeter completed the trifecta with the win, after taking silver in the 100-meter and bronze in the 200-meter.
