You don't need a route book; you get that from the rallymaster when you register for a rally. You ought to then go over the things you do before you even leave the rally start, like synchronize a timepiece, prepare the vehicle and prepare the rally instructions. You should also discuss (for the viewer's benefit) what you and your navigator are doing, so the viewer will understand you are not just on a scenic drive.
This video is fine for what it does say. For example, you don't really need a calculator until you move up from the novice class. All you really need is a car with a good speedometer/odometer and a good wristwatch. Most of the more important parts of a rally are missing, such as the procedure for the start, what you should do at a checkpoint, and some basic terms like FreeZone (FZ), and Transit Zone (TZ) and how to read the route instructions.
This is one form of TSD rallying. It might be called "alpine" or "tulip" format. The video does a good job of explaining how to run this type of event. Thanks for putting it up.
