(Portland, OR) -- Thousands hit the streets Sunday for the Portland Marathon and half marathon, with nearly 12-thousand participants - about three-thousand more than last year. Organizers credit the jump to a new sponsorship with Nike. Among the highlights, 20-year-old Micah Margason set a course record, while his fiancé, Malia Harvey, ran her first half marathon in honor of her late father. Runners of all ages took part, including 71-year-old Glen Buck, who completed his first half marathon with help from family. The event ran smoothly, with no disturbances reported along the route.
