Michael Phelps, Misty May-Treanor Unveil Their Olympics Limited Edition Wheaties Boxes (PHOTOS)

Olympian Michael Phelps can add yet another honor to his highly decorated career: Wheaties coverman. The 18-time gold medalist and fellow Olympian Misty May-Treanor debuted their limited edition Wheaties boxes on Thursday, which will hit supermarket shelves in September.

Phelps, 27, finished the 2012 London Olympic Games as the most decorated Olympian of all time with 22 medals. Meanwhile, May-Treanor, 35, has won more tournaments than any other professional female volleyball player in the sport. The two seemed like an obvious choice for the cereal brand, which has a history of celebrating the top American athletes.

The record-breaking swimmer has called the London Olympic Games his last, but he will continue to work with his foundation, the Michael Phelps foundation, which aims to promote swimming and healthy living across the U.S.

Phelps said the following in a statement: “I received a lot of comparisons throughout my career, but I always wanted to be the best that I could be. I wanted to do something that nobody else had done before and I wanted to change the sport of swimming. Thanks to Wheaties and their support of my Foundation, I hope that my accomplishments will help inspire others to pursue their dreams.”

As for May-Treanor, she walked away from the London Games as the first in her sport to win three gold medals. “My message to athletes everywhere is to never give up, ever,” she said in a statement. “If someone says you can’t do it, try harder.”
