Michael Phelps reiterated his retirement from swimming as the London Olympic Games set to begin in less than 24 hours.

In a report on Thursday from Bill Shaikin of The Los Angeles Times, Phelps said there's no way he'll compete in the 2016 Olympics in Rio de Janiero and that he's looking forward to living life on his own time after this summer:

"Just to relax," he said. "Not to answer to anybody. Not have somebody tell me where to go, when to go there, what to do, just kind of be on my own time."

Phelps, 27, said he's also looking forward to doing everything from working with children to skiing.

After the 2008 Olympics in Beijing, he knew he wanted to swim again. But he won't have that same drive after this Olympics, he said.

"The biggest thing I will always stand by is that I won’t swim past the age of 30," Phelps said. "That is something I don’t want."
