Big story: Allyson Felixs (above) third try for gold in the 200 after two silver finishes. She ran a world-best 21.69 seconds at the U.S. trials after more than a week of suspense over her tie for third in the 100 with Jeneba Tarmoh. Felixs medal chances in the 100 are slim but she kept her spot in that race because she considers it good preparation for the 200, and her trials performance supported that. Felix is in the pool for both relays.
Top U.S. prospects: World 100 meter champion Carmelita Jeter, who won the final at the U.S. trials and was second in the 200. Sanya Richards-Ross, whos attempting a 200-400 double and likely to run a relay. Pole vaulter Jenn Suhr, who won silver at Beijing. Lolo Jones, part of a strong 100-meter hurdles contingent with Beijing champion Dawn Harper and Kellie Wells.
Others to watch: Jamaicans Shelly-Ann Fraser-Pryce in the 100 and 200 and two-time 200 gold medalist Veronica Campbell-Brown. Yelena Isinbaeva of Russia, pursuing a third straight pole vault gold medal after no-heighting at her last warmup event. Australias Sally Pearson has dominated the 100-meter hurdles but lost to Wells at a recent London meet. Jessica Ennis, the 2009 world heptathlon champion, carries the countrys medal hopes in the sport.
Little-known fact: At the 1948 London Games, American Alice Coachman became the first black woman to win an Olympic gold medal when she won the high jump with a leap of 5 feet, 6 1/8 inches.
