For all intents and purposes you could improvise. The runway they give is the heading of the runway (this is how it works in real life btw). So for example if you're told to taxi to runway 01 the takeoff roll will be on heading 010 or runway 26 the heading is 260 for the takeoff roll. Basically runway number is the heading of that runway. Knowing this you can approximate the route you need to take to the runway.
