Orienteering is an outdoor sport that involves navigating through unfamiliar terrain using a map and compass. There are different types of orienteering including cross-country, score, and line orienteering which involve finding control points around a course in the fastest time or by accumulating the highest score. Proper technique includes thumbing the map, choosing whether to climb or detour obstacles, aiming off control points, using handrails, and pace counting to estimate distances traveled. Pace counting involves counting every step or every other step taken and varies based on terrain from 65-90 paces per 100 meters on level ground.
