At 41, four-time Olympian and Boston and New York marathon champion Meb Keflezighi is starting his transition into athletic retirement

Running great Meb Keflezighi says he'll do just two more marathons in his career, to end with 26 -- the distance in miles of the event. The four-time Olympian and winner at Boston and New York is 41 now, and starting to transition to a post-marathon world.
