Foot orienteering is the oldest formal orienteering sport, and the one with the most "starts" per year. Usually, a FootO is a timed race in which participants start at staggered intervals, are individually timed, and are expected to perform all navigation on their own. The control points are shown on the orienteering map and must be visited in the specified order. Standings are determined first by successful completion of the course, then by shortest time on course.
