PHILADELPHIA – Olympian Deena Kastor set an American women’s record for the half marathon with a time of 1 hour, 7 minutes, 53 seconds Sunday in the 28th annual Philadelphia Distance Run.

Kastor, 32, of Mammoth Lakes, Calif., eclipsed the previous mark of 1:08:34 established by Joan Benoit Samuelson of Freeport at this event in 1984. It’s the second of Benoit Samuelson’s major records to be broken by Kastor. Two years ago, Kastor set the U.S. mark in the marathon.
