Moses Mosop of Kenya set a course record in cruising to victory in the Chicago Marathon on Sunday in a race tempered by the first death in the event in four years after a runner collapsed near the finish line.

Korir finished 38 seconds behind Mosop in second place. In a post-race interview, Mosop said he had been prepared to challenge for a course record, but not the world record because a leg injury had limited his training.
