BEIJING, China (AP) - Michael Phelps set a world record Sunday to win his first gold medal of the Beijing Olympics.
He beat rival Ryan Lochte in the 400-meter individual medley with a time of 4 minutes, 3.84 seconds.
Phelps is trying to break Mark Spitz's record of seven gold medals. He crushed his old mark of 4:05.25 in the 400 IM, set in June at the U.S. Olympic trials.
Laszlo Cseh of Hungary rallied to take the silver medal in 4:06.16. Lochte won bronze.
