It is the first time that the para-equestrian world championships will be run concurrently with the seven other FEI disciplines.
Organiser Hope Hand said that many countries would be seeking out horses for use in the upcoming months before the WEG in September. "They will be looking for horses for riders in all five of the Para-Equestrian grades - IV, III, II, Ia and Ib," she said.
"A big moving, well behaved Prix St Georges horse would be suitable for a Grade IV rider with the training and ability perform correct simple changes, walk pirouettes, half pass trot and canter, collected, medium and extended canter with a clear difference.
"The grade III riders will require a good moving horse with well established lateral movements, collection and medium in trot and canter and again good walk pirouettes. "Grade I and II is performed at the walk and trot but a Prix St Georges quality walk and trot would be ideal," Hand said.
"This is a chance to experience the WEG from the inside and be an owner of an international superstar that can change someone's life."
