BOSTON (CBS) – It took all of 26.2 miles for 28-year-old Kenyan Sharon Cherop to edge out fellow Kenyan 27-year-old Kenyan Jemima Sumgong and win a very close race in the women’s elite division of the 2012 Boston Marathon.

Cherop pulled ahead on the final straight away along Boylston Street, crossing the finish line with an unofficial race time of 2:31:50.

Sumong finished in second place, just seconds behind Cherop, who collected $150,000 with the win.

This is the fifth straight year that the women’s race came down to a sprint down Boylston.

Cherop’s winning 2012 time was more than nine minutes slower than her 2011 third place Boston Marathon finish time of 2:22:42.

The course record of 2:21:45 was set in 2002 by Kenya’s Margaret Okayo.
