BOSTON (AFP) – Athens Olympic marathon silver-medal winner Meb Keflezighi will run the Boston Marathon for the first time in March, race sponsors announced here yesterday. Keflezighi finished third in the New York City Marathon two months ago, the best marathon showing by an American in 2005. «The Boston Marathon is internationally recognized and has a great tradition, and I know there will be high expectations for me,» Keflezighi said. «I always run to win. It’s the motto that I live by.» The 30-year-old Californian’s Olympic effort in Greece was the best by a US runner in the marathon since Frank Shorter’s 1976 silver-medal performance in Montreal. Only 70 days later, Keflezighi finished second in New York with a personal best of 2 hours, 9 minutes and 53 seconds. «Meb is a great competitor, and he will compete to win,» Boston Athletic Association Executive Director Guy Morse said.
