DULUTH — Bazu Worku broke away from the leaders about 19 miles into the race and set a new men’s course record 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 the course record. He crossed the finish line in Duluth in an unofficial two 2 hours, 11 minutes and 12 seconds to beat Kenya’s Ernest Kabenei.

Worku finished nearly 4 minutes better than 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.
