Ranching Heritage Challenges This is an exclusive opportunity for Ranching Heritage-bred horses. The AQHA Ranching Heritage Challenge highlights the versatility, soundness and willing attitude of American Quarter Horses born and raised on a ranch. First, the goal of the Ranching Heritage Breeders program is to recognize AQHA’s ranching members who have steadfastly continued to maintain the ranching tradition by raising American Quarter Horses for use working cattle. Second, through a series of ranch horse competitions, the Ranching Heritage Challenge is intended to increase the demand for ranch horses by providing an opportunity for ranches and horse owners to compete in a unique ranch horse competition with a significant purse.
