Thank Heaven for Little Girls and Big Ones Too - S1-E4
Other mistake: Magnum gets inside the Waikiki Natatorium War Memorial climbing athletically over the closed gate. The bad guy comes roughly from the same direction, but given his physical state, one wonders how could he accomplish such a feat - it is conveniently kept off camera, but he comes from a direction with no gates. To beat him to the finish, Rick picks another direction entirely just walking around the bleachers! And they all end up at the same location.
