It depends on the light levels and what shutter speed/ Aperture you use. If you have any ND grads then you could use them as well. I used ND grads so reducing the shutter speed to about two seconds, but you can get blur at 60/s handheld. Set up you camera on a tripod, select you Aperture at F11 and shutter speed at 30/s then press you shutter button half way and check what Iso you camera shows. Adjust until your Iso is about 200. Take a shot and checked if it's blurred enough, if not reduce your shutter speed 15/s and try again.
