Michael Phelps set for London trials

OMAHA, Neb. -- Michael Phelps and Ryan Lochte renew their rivalry at next week's U.S. Olympic trials, where both swimmers could face each other in six events.

They'll open the eight-day meet in Omaha, Neb., on Monday in the 400-meter individual medley, a grueling event that Phelps had said he wasn't going to swim anymore after the 2008 Olympics, where he won a record eight gold medals. He holds the world record in the event.

Their other events against each other will be the 100 and 200 freestyle, 200 backstroke, 200 IM and 100 butterfly. Phelps is entered in the 200 butterfly as one of his seven events.

Lochte is entered in a total of 11 events, including the 50 free, 100 breaststroke, 200 fly and 400 free, but is unlikely to swim all of them. Swimmers can scratch out of an event up until the end of finals the day before their scheduled event.

Phelps' other world records are in the 100 and 200 butterfly. He holds the American record in the 200 free.

Lochte's lone world record is in the 200 IM from last year's world championships, the first world mark set since high-tech bodysuits were banned.

On the women's side, 17-year-old Missy Franklin and Olympic veteran Natalie Coughlin are each entered in five events. Dara Torres is only entered in the 50 free in an attempt to make her sixth Olympic team at 45.
