US breaks 27-year-old record in women's 4x100

LONDON – Carmelita Jeter crossed the finish line pointing the baton at the clock showing a world record of 40.82 seconds Friday night as the United States won the women's Olympic 4x100-meter relay for the first time since 1996.

Tianna Madison, 200-meter champion Allyson Felix and Bianca Knight gave the U.S. a big lead heading into the anchor leg by Jeter, the 100 silver medalist.

Their time smashed the old record of 41.37 by East Germany in 1985.
