Hampstead Bowmen are a Target Archery Club and Target Archery is governed by the World Archery Federation, abbreviated WA and Olympic rules are derived from the WA rules. WA is the International Olympic Committee's (IOC) recognized governing body for all of archery. In the UK, GNAS (Grand National Archery Society) of Great Britain, is the governing body and has now re-branded itself as Archery GB.
Target Archery is the most popular form of archery, in which members shoot at stationary circular targets at varying distances. All types of bow - longbow, barebow, recurve and compound - can be used.
In Great Britain, Imperial rounds, measured in yards, are still used for a lot of tournaments and these have slightly different rules to WA (metric) rounds, which are used internationally. Archers are divided into seniors and juniors, with juniors being those under the age of 18.
