This week we did a 4 Night cruise on the Disney Dream. I tried to do some running on vacation to keep up with the amount of eating I did on the cruise. On Monday morning, as we pulled into Nassau, Bahamas, I ran 3 miles around the external jogging track of the ship.
One mile on the ship takes 2.5 laps.
Here is a video I did for 1 lap around the ship. I should have recorded it walking, but did it while I ran, so it is a little shaky. But you should be able to get the idea of the coolness of running around the cruise ship. With the ship running at about 15 knots, in one direction of the ship you have an awesome tailwind, where the other side is a little more challenging with a serious head wind.
