At the 2008 Beijing Olympics, the Jamaican track team almost completely dominated the medal podium in the short-distance sprints, winning gold in the all of the men's and women's 100- and 200-meter races, in addition to two silvers and a bronze.
This year's women's 200-meter race promises to be a more diverse field. Though the Jamaicans are still represented by defending champion Veronica Campbell-Brown and defending 100-meter champion Shelly-Ann Fraser-Pryce, the American trio of Allyson Felix, Carmelita Jeter and Sanya Richards-Ross, as well as a few other international competitors, hope to knock the Jamaicans off the medal stand.
The 200-meter semifinal will be run on Tuesday, Aug. 7, at 3:25 p.m. EDT, with the final on Wednesday, Aug. 8, at 4 p.m. EDT.
Here is a look at the four favorites to win medals in the 200 meters, as well as three dark horses who could find their way onto the medal podium.
