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.
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.
