Frank Shorter, the American marathoner who won an Olympic gold medal in 1972 and made running cool, isn’t the kind of guy to say, “I told you so.”

So I will say it for him: He told you so.

For years, when someone would ask him who he thought would win the next major marathon, he told me, his answer was always the same: “I don’t know who it will be, but the person will be from a country without an antidoping agency that is totally independent, audited and doesn’t have a dog in the fight.”

Save for a few victors here and there, Shorter — a former chairman of the United States Anti-Doping Agency — was right.

African countries like Kenya have dominated the major marathon scene for years, and Sunday’s New York City Marathon was no different. It was a Kenyan sweep when Wilson Kipsang and Mary Keitany finished first and grabbed their $100,000 paychecks.
