OMAHA, Neb. Holding off one of his best friends, Michael Phelps started his second attempt to break Mark Spitz's Olympic record with another epic swim.
Less than an hour later, the teenager he compares to a little sister joined Phelps in the record book.
Phelps set a world record in his first event of the U.S. Olympic swimming trials, touching just ahead of Ryan Lochte to win the 400-meter individual medley in 4 minutes, 5.25 seconds Sunday night.
Katie Hoff matched her former North Baltimore teammate in the 400 IM, taking down the women's mark in 4:31.12.
Quite the start to the eight-day meet.
Wearing the high-tech Speedo LZR Racer, Phelps beat his own mark of 4:06.22, set at last year's world championships in Australia when he turned in one of the greatest performances in swimming history with seven gold medals.
After saying he had no fear of Phelps, Lochte proved it by also going under the previous record. But his time of 4:06.08 was only good enough for second with Phelps in the next lane over.
"That was probably one of the most painful races of my life," the winner said. "Everything was left in the pool. I definitely would not have been able to do it without Lochte beside me. He's a great friend and a great competitor. I love racing him."
The 19-year-old Hoff playfully described by Phelps as the little sister he never had showed no signs of the nervousness that ruined her first trip to the Olympics four years ago. Hoff dipped under record pace on the breaststroke leg and held on with her freestyle to beat Stephanie Rice's mark of 4:31.46, set in March at the Australian Olympic trials.
"Stephanie really raised the bar when she broke my old record," Hoff said. "I'm just excited for Beijing, and I think it's going to be a really tough challenging race with her."
Like Phelps, Hoff also was wearing the revolutionary Speedo suit, which has been worn for 40 of the 44 world marks set since it was unveiled in mid-February.
"It definitely gave me a few tenths," Phelps said. "At the end, when I was getting a little tired, the suit gave me a little extra edge."
Phelps was slightly off world-record pace after the opening butterfly, but he had a body-length lead on Lochte as they switched to the backstroke.
The minus sign indicative of a swimmer under record pace flashed on the board when Phelps made his flip turn on the back, sending the crowd at the Qwest Center into a frenzy. But Lochte was starting to close the gap, and he nearly pulled even as they headed toward the far wall in the breaststroke.
Lochte, a world recordholder himself, was less than a second behind at the 300 mark and looked poised to pull off a monumental upset. He and Phelps went at it stroke for stroke over the final two laps, but Phelps never relinquished his lead.
After his arm touched the wall ahead of Lochte's, Phelps looked at the scoreboard, saw the record and thrust his right fist in the air. Then he slapped the water.
Lochte, breathing heavily, grinned as Phelps celebrated. They hugged in the water, and then again on deck while the fans saluted them both with a standing ovation.
"He looked great, and what an epic swim," said Phelps' coach, Bob Bowman. "One of the best swims I've ever seen."
Robert Margalis finished third, more than 7 seconds behind the top two.
"That's absolutely incredible," Margalis said. "I'm a swimming fan as much as I am a swimmer. I'm happy for those guys. It was a fun thing to be a part of."
Phelps won six gold medals and two bronzes at the Athens Olympics, just missing Spitz's record of seven wins at the 1972 Munich Games. Phelps who turns 23 on Monday is determined to knock off the mark in Beijing.
Lochte was the top qualifier in the morning prelims.
"After this morning, he told me he was tired," Phelps. "I knew he wasn't that tired."
