Orienteering is a group of sports that requires navigational skills using a map and compass to navigate from point to point in diverse and usually unfamiliar terrain whilst moving at speed. Participants are given a topographical map, usually a specially prepared orienteering map, which they use to find control points. Originally a training exercise in land navigation for military officers, orienteering has developed many variations. Among these, the oldest and the most popular is foot orienteering. For the purposes of this article, foot orienteering serves as a point of departure for discussion of all other variations, but almost any sport that involves racing against a clock and requires navigation with a map is a type of orienteering.
Orienteering is included in the programs of world sporting events including the World Games (see Orienteering at the World Games) and World Police and Fire Games.
Orienteering sports combine significant navigation with a specific method of travel. Because the method of travel determines the needed equipment and tactics, each sport requires specific rules for competition and guidelines for orienteering event logistics and course design.
Adventure racing is a combination of two or more disciplines, and usually includes orienteering as part of the race.
At international level, the International Orienteering Federation (IOF) defines rules and guidelines which govern four orienteering sports: foot orienteering, mountain bike orienteering, ski orienteering, and trail orienteering. It is based in Finland and it claims on its website to aim to "spread the sport of orienteering, to promote its development and to create and maintain an attractive world event programme." Since 1977 the IOF has been recognised by the IOC
