The Yorkshire and Humberside Orienteering Association, (YHOA), exists to encourage, promote, co-ordinate and control the sport of Orienteering in Yorkshire and the former county of Humberside. It is affiliated to the English Orienteering Council and to the British Orienteering Federation (BOF). It recognises BOF as the ruling body for the sport of Orienteering in Britain and will abide by its directions, rules of competition and bye-laws.
The Association is a federation of the orienteering clubs in the region comprising the open clubs AIRE, CLARO, EBOR, EPOC, HALO and SYO and closed clubs SHUOC, HUOC and LUOC. The affairs of YHOA are conducted by an Executive Committee made up, principally, of representatives of the constituent clubs.
The purpose of the Association is to coordinate fixtures and other activities between its member clubs, to promote the development of orienteering in the region, to organise relevant training courses, to promote and coordinate major regional events such as the British Championships and to act as a communication link between the clubs and BOF council. The Association nominates individuals to represent the region on BOF council and on BOF committees. The Association owns and manages, on behalf of the clubs, the electronic (Sport Ident) punching system that is used at orienteering events in the region.
