Mebrahtom Keflezighi was the first American in 27 years to win the New York City Marathon. Cameron Stracher, the publisher of the New York Law School Law Review and author of a forthcoming book about the American running boom in the 1970's and 1980's, discusses why he thinks American running was on the decline and what Keflezighi's win means for the future of the sport in the United States - and what an All-American runner means anyway.
