The U.S. track team came up just short. And boy, are they ecstatic about it.
Charged with the daunting goal of winning 30 medals at the London Games, the largest team in the U.S. Olympic contingent came through with 29. That's six more than it won four years ago in Beijing and the most since the 1992 Barcelona Games, when track and field hit the 30 mark.
Led by Allyson Felix's three gold medals, including the world record-setting 4x100 relay, the U.S. team also won nine titles, two more than in Beijing. The disappointing performance in China spawned an unflattering report called "Project 30" -- a look at the track team's flawed system that concluded with a goal of winning 30 medals this year. The team came into the final day of the Olympics with 29 medals and a contender in the marathon in Meb Keflezighi. He finished fourth.
The United States won 11 more medals at the track than second-place finisher Russia and 17 more than Jamaica.
Sanya Richards-Ross, 27, said she wants to compete in Rio in 2016 but can't fully commit to anything yet. She plans to run the world championships next year, then take a year off.
This was her third Summer Games this year, and she earned her first individual gold medal in the 400 meters and a gold in the 4x400-meter relay, giving her four golds and a bronze.
IOC President Jacques Rogge said efforts to fight doping at the Olympics were a success.
Through Sunday morning, only one athlete tested positive for a banned substance on the day of competing at the Games. Seven more were caught in doping controls conducted since July 16.
The IOC had said this would be its most extensive Olympic anti-doping program. It took almost 6,000 urine and blood samples.
Diana Taurasi's already impressive Olympic resume isn't finished. The U.S. shooting guard has three gold medals and says she will be at the 2016 Rio Games looking to win a fourth.
Taurasi, 30, averaged a team-high 12.4 points in London. Bolt's night out
Usain Bolt hotfooted it from Olympic Stadium Saturday night to a party nearby in East London and turned DJ to entertain the packed crowd.
Bolt then dashed to Movida, in London's West End. Club spokeswoman Martina Pokorna said the group included Bolt's teammate Yohan Blake and British swimmer Rebecca Adlington.
She said they were given a Nebuchadnezzar -- the equivalent of 20 bottles -- of Ace of Spades champagne. It has a retail price of $125,000.
"They left at 6 o'clock this morning," she said.
The London Olympics may be remembered as the event that drove home the power of social media.
Twitter estimates there were more than 50 million tweets about the Olympics, at a pace of 80,000 per minute after Bolt won the gold in the 200 meter. Facebook saw the number of fans of athletes soar: American gymnast Gabby Douglas had 14,358 followers on July 27 and 540,174 less than two weeks later.olympics
