DULUTH, Minn. — Bazu Worku broke away from the leaders about 19 miles into the race to win the 37th annual Grandma's Marathon.

The 22-year-old Ethiopian, running in his first Grandma's Marathon, finished nearly 4 minutes better than his personal best. The Duluth News Tribune reports (http://bit.ly/11STWH6 ) he crossed the finish line in Duluth on Saturday in an unofficial two 2 hours, 11 minutes and 12 seconds to beat Kenya's Ernest Kabenei.

But Worku wasn't able to beat the course record set 32 years ago by Minnesota's Dick Beardsley, who won the 1981 title in 2:09:37.

Sarah Kiptoo of Kenya won the Grandma's Marathon women's title in a course-record 2:26:32, which was 33 seconds better than the old mark of 2:27:05 set by Fira Sultanova in 2003.
