Muenzer retires

Olympic track champion Lori-Ann Muenzer, who won the sprint gold medal at the 2004 Athens Summer Games at the age of 38, announced Monday she is retiring from cycling. She plans to concentrate on her business and devote time to a program she's established to develop young cyclists.

Leaving the sport that has consumed her for over 17 years wasn't an easy decision for the Toronto native, who now lives in Edmonton. "I really thought long and hard about it," Muenzer, 40, told The Canadian Press. "To be able to have the ultimate performance you have to have so many things in alignment to make it happen."
