Michael Phelps and his U.S. teammates broke the world record in the men's 800-meter freestyle relay at the world swimming championships Friday.
Phelps, Ryan Lochte, Klete Keller and Peter Vanderkaay touched first in 7 minutes, 03.24 seconds, lowering the time of 7:04.66 set by Australia at the 2001 world championships in Fukuoka, Japan.
It was Lochte's second world record of the night to go with his new standard in the 200 backstroke.
Phelps swam the leadoff leg, getting the Americans under world-record pace on the first of his four laps. His 200 split of 1:45.36 wasn't good enough to lower the world record of 1:43.86 he set in winning the 200 free Tuesday.
Australia took the silver and Canada earned the bronze.
