 Competitive gliding in the UK takes place between May and September . Regionals are local competitions , organised and run by one of the bigger gliding clubs in the region , and represent the entry level to glider racing . Races are handicapped according to glider performance , and normally take place over nine days . Success in the regionals allows pilots to progress to the nationals , where there are five classes of competition . These are based on glider performance , the lowest being club class , and then progressing through standard ( maximum 15 metres ( 49 ft ) wingspan , and flaps not permitted ) , 15 metres ( 49 ft ) ( as standard , but flaps are permitted ) , 18 metres ( 59 ft ) ( maximum 18 metres ( 59 ft ) wingspan ) , and finally open @-@ class ( no restrictions ) . Success at national level can lead to a place in the national team and competition at international level .
