American runner Sanya Richards-Ross won the first individual Olympic gold medal of her track career, placing first in the women’s 400-meter with a time of 49.55 seconds on Aug. 5 during the 2012 Summer Olympic Games in London.

Fellow African-American sprinter DeeDee Trotter placed bronze at 49.72 seconds, just two-hundreds of a second behind British runner Christine Ohurhuogu, also a woman of color.

For the U.S., it was the first gold medal won in a track and field event so far in this summer’s games. For Richards-Ross, it was a moment of personal redemption as she had to settle for a disappointing bronze medal in the women’s 400-meter four years ago during the 2008 Olympic Games in Beijing.

She made sure she wouldn’t disappoint herself this time around.

“I just kept saying, ‘You can do this, you can do this,’” Richards-Ross said. “I just dug really deep and I’m very happy.”

Richards-Ross, born and raised in Kingston, Jamaica, moved to the U.S. at the age of 12. She has also won six gold medals in other world championship events, including a win in the 400-meter of the 2012 World Indoor Championship in Turkey. She also won a gold medal as a member of the U.S. 4×400 meter relay team during 2008 Olympic Games and the 2004 Olympic Games in Athens.

Richards-Ross was also a track champ at the University of Texas, where she met her husband, Aaron Ross, a cornerback for the two-time Super Bowl champion cornerback for the New York Giants.

Meanwhile, Colombian track star Caterine Ibarguen captured a silver medal in the women’s triple-jump with a leap of 14.80 meters (about 48 feet).
