It seems like the gerbil wheel is an old sci Fi trope.

Is the novelty of us that it's sideways?

Yes: on Earth I imagine this isn't possible (the required centrifugal force to generate the friction needs you to be travelling much faster than a human can run), though I haven't done any calculations.

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.
