Nope - There are treadmills in the Gym, although if, like me you are tall, the way they are positioned means you are liable to be pitched into the ceiling if the seas are anything less than smooth and it can be disconcerting to have the floor disappear from under you mid stride if the ship is pitching. You can run around the promenade deck, but are restricted to after 8am and it's narrow which puts you in conflict with people who are promenading, and there are plenty, moving very slowly as expeced given the demographic.
