> on Earth I imagine this isn't possible Only if you use a vertical wall as the "floor". If you set the "floor" at, say, 45deg, and then spin the centrifuge up enough so that the floor feels level, you could practice running at √2g (~1.4g). Then vary the floor angle and centrifuge speed for various g levels while running on what feels like a level surface.
