Michael Phelps, who has kept his plans for this summer's London Olympics a secret, has entered seven races at next week's U.S. Olympic Trials, including the grueling 400-meter individual medley, reports The Baltimore Sun's Jean Marbella.

According to Marbella's report, Phelps signed up for the 200 and 400 individual medley, the 100 and 200 freestyle, the 100 and 200 butterfly and the 200 backstroke.

Phelps famously won all eight events he entered at the 2008 Beijing Olympics, setting a record for most gold medals in a single Games. He has the opportunity in London to become the most decorated Olympian of all-time with three more medals, which would move him past Soviet Union gymnast Larisa Latynina's career total of 18. (Some would argue Phelps is already the greatest Olympian ever by virtue of his record 14 gold medals).

Phelps' schedule for the Olympic Trials is probably too ambitious to be completed. Because he is likely to be chosen for relay teams at the Olympics, it's unlikely he will attempt all seven individual events. With relays, he would be looking at 10 events, even more than the eight he raced in each of the past two Olympics. He has repeatedly stated he plans to cut back his schedule for London.
