Deck 12 had a jogging (or walking) track that encircled the ship. It seemed to be more heavily used in the early morning hours, but there was some usage all day long. As you can see from this photo, there were marked lanes to control 'traffic', although not shown here, there were various markings to help you determine the distance covered. The surface of the track was a soft, sponge-like fabric, which was easy on your feet and spine.
