Welcome to American Horsemen Challenge Association. AHCA is a timed equine obstacle course event. Courses are designed for all breeds and disciplines. AHCA has divisions for all ages and all levels of riders and horses. Rules allow riders to use strategy when completing an obstacle to showcase the horses training and the partnership with the rider.
