Meet the record Smashers

Pointing the baton at the clock showing the world-record time of 40.82 seconds, Carmelita Jeter anchored the United States on Friday night to its first Olympic gold medal in the women’s 4×100-meter relay since 1996.

Tianna Madison, 200-meter champion Allyson Felix and Bianca Knight gave the US a big lead heading into the anchor leg by Jeter, who already owned a silver medal from the 100 and a bronze from the 200 in London.
