LONDON -- David Rudisha of Kenya broke his own world record to win the Olympic 800-meter gold medal Thursday.

Rudisha won the final in 1 minute, 40.91 seconds. His old mark was 1:41.01.

Nigel Amos of Botswana took silver and Timothy Kitum of Kenya got the bronze.

Americans Duane Solomon and Nick Symmonds finished fourth and fifth.

Symmonds never thought he'd crack the 1:43 barrier. Well, he did. But it still wasn't good enough for a medal.

"On one point, I'm crushed and devastated, but on the other, to do something I never thought I'd be humanly capable of, I've got really mixed emotions," Symmonds said. "I really need a pint right now."

Symmonds ran a career best of 1:42.9.

"To run a personal best at 28 years old, I feel invincible right now even though I don't have a medal around my neck," he said.
