Orienteering is a sport involving navigation with map and compass. The traditional form (sometimes referred to as Foot Orienteering or Foot-O) involves cross-country running, though other forms have evolved. Rules and principles are defined by the International Orienteering Federation.
The English name derives from Swedish orientering, "orientation".
Participants have a map, usually of an area with which they are unfamiliar, and a compass. They attempt to visit, in sequence, control points that are indicated on the map, as quickly as possible.
