Field archery consists of a series of targets set out over natural terrain, which may include woodland, slopes, open ground or water features. Archers progress around the course in small groups, shooting each target in sequence until the course is completed. A round typically takes most of the day, with breaks taken along the way. The structure of competitions and the rules of shooting vary depending on the governing body under which the shoot is held, and targets may include roundels, paper faces depicting animals, or three-dimensional foam animal targets, each with designated scoring areas and either marked or unmarked shooting distances.
