Phelps entered seven events in the eight-day meeting that begins today in Omaha’s 13,200-seat CenturyLink Center, but as of Saturday he wouldn’t confirm if he actually planned to race the first event on his docket — today’s 400m individual medley. Phelps has won it at the last two Olympic Games, but after Beijing vowed never to swim the punishing event again in major competition.
