The United States of America are looking to close out the 2012 London Olympics on a high note, which would include beating the dominant Jamaican runners in the women's 4x100 meter final at Olympic Stadium on Friday. And thanks to a world record time, they Americans did just that.
The team of Tianna Madison, Bianca Knight, Allyson Felix and anchor Carmelita Jeter led the United States to the gold medal, setting a new world record with a time of 40.82 seconds.
Jamaica would finish with the silver medal, finishing in a time of 41.41, while the team from the Ukraine would take home the bronze with a time of 42.04.
