As defined on the website of OUSA, orienteering is a competitive international sport that combines racing with navigation. It is a timed race in which individual participants use a specially created, highly detailed map to select routes and navigate through diverse and often unfamiliar terrain and visit control points in sequence. Courses also can be enjoyed as a walk in the woods, with difficulty levels from beginner to expert offered at most events. Competitive age groups range from younger than 10 to older than 90.
A standard orienteering course consists of a Start, a series of Control sites that are marked by circles, connected by lines and numbered in the order they are to be visited, and a Finish.
Most orienteering events use staggered starts to ensure that each orienteer has a chance to do his or her own navigating, but there are several other popular formats, including relays and events in which the orienteer must find as many controls as possible within a specified time. Also, most events are foot orienteering events, but there are also ski, bike, canoe or other orienteering events
