A-B tasks
Navigation tasks in which two map points A and B must be connected by the shortest permitted route.
A-B tasks are a classic form of navigation rallying. Two points, A and B, are marked on a map extract, and the crew must find and drive the shortest permitted connection between them. What counts as permitted is defined by the organiser – for example, whether only certain types of road may be used.
Often several A-B tasks are chained together: the end point of one task is the start point of the next. In this way the whole route is built up from many short connections. The appeal lies in map reading and in cleanly determining the shortest connection. Misread a junction and you drive a detour, collecting penalty points at the controls.
