Injury forces Samuelson out of Chicago Marathon

Joan Benoit Samuelson has pulled out of the Chicago Marathon because of a knee injury, the Chicago Tribune reported Thursday.

The 60-year-old Samuelson, a Cape Elizabeth native who lives in Freeport, had been aiming to become the first woman 60 or older to beat three hours in Sunday’s race.

Samuelson won the 1985 Chicago Marathon in 2 hours, 21 minutes, 21 seconds, an American record that stood for 18 years.
