Navigation and Regularity
There are many ways of defining the route you have to take on the rally, most of which require plotting onto the map. Most of the popular methods are covered in the HRCR Navigation Handbook, which you can download and print from the link below. Grid references, spot heights, tulips, herringbones, etc. are all explained. We always use the Ordnance Survey 1:50000 Landranger maps and you can learn a lot by studying a map with reference to the map's key.
Something you'll need when you want to accurately control your average speed is a set of speed tables, giving you time vs distance for a wide range of average speeds. Quite good enough to start you off is the Average Speed Table that you can download and print off from the link below.
