The world's fastest man is set to compete for an unprecedented “triple-double” at the London Olympics Saturday.

Usain Bolt and his fellow Jamaican sprinters are seeking a win in the 4×100-meter relay, with Bolt running the anchor.

A victory would follow Bolt's wins in the 100- and 200-meter sprints. He won all three races at the 2008 Beijing Games.

He and his teammates will face a tough U.S. squad anchored by 100-meter bronze medalist Justin Gatlin.

Also Saturday, the U.S. will take on France for the gold medal in women's basketball. The U.S. has captured 40 straight Olympic games and is seeking its fifth-straight Olympic gold.

In early results Saturday, France's Julie Bresset capped an extraordinary year by riding to victory in the women's mountain-bike cross country.

Russia's Sergey Kirdyapkin won a gold medal in the men's 50-kilometer walk, and Britain's Ed McKeever powered his way to gold in the inaugural men's 200-meter K-1 canoe sprint regatta.

In the medal count, the U.S. has been pulling away from China and is nearing 100 total. Russia remains in third place and Britain in fourth. The U.S. is slightly ahead of China in gold medals.
