Tom Dolan won the 400-meter individual medley at the U.S. Swimming National Championships.
Dolan, 21, the Olympic gold medalist, world record holder and world champion in the 400 individual medley, was on world record pace for the first 350 meters. He won in 4:17.13, fastest in the world this year.
Dolan holds the world record of 4:12.30. It was only his third meet since the Olympics and first one he rested and shaved for.
"I'm coming off a great summer of training," Dolan said. "It's been an interesting year since the Olympics. It felt good to get in there and race again. It's tough when you get to where I am in the sport where you are pushed to go your best time. Unfortunately for me in this event that's a world record."
Dolan, an asthmatic who has also suffered fatigue problems, holds the world record of 4:12.30. It was only his third meet since the Olympics.
Amanda Beard, 15, the American record holder in the 100-meter breaststroke, failed to reach the final in the event. Beard was ninth, missing the eight-swimmer final by 1/1 00th of a second. At the 1996 Olympics Beard earned silver medals in the 100 and 200 breaststroke events and was a member of the 400-meter medley relay.
Olympian Cristina Teuscher won the 200-meter freestyle in 2:01.00. Teuscher finished a disappointing sixth in the event at the Olympics in Atlanta but came back to win a gold medal as a member of the 800-meter freestyle relay team, where she posted the fastest 200-meter freestyle split in U.S. history.
Kristy Kowal, 18, won the 100-meter breaststroke in 1:08.80.
