It was the closest call of the Last Great Race. At the end of the 1,000-mile Iditarod Trail Sled Dog Race in 1978, Dick Mackey edged defending champion Rick Swenson by a single second. Judges ruled Mackey the winner because his dogs crossed the finish line ahead of Swenson's. Over three decades, Swenson would become the race's only five-time winner, while Mackey's sons Rick and Lance added their own championships to the family tree. On Thursday, the Alaska Sports Hall of Fame inducted the photo finish as one of the state's great athletic moments.
