A keyhole race is a speed event commonly seen at equestrian events and
gymkhanas, in which the horse and rider team with the fastest time in completing the event wins. Horses running this event must have speed, but also the agility to stop quickly in full stride, turn, and bolt directly back into a run.
The obstacle course is a pattern, usually marked with white powder (commonly flour or powdered chalk) poured into a "keyhole" shape in the dirt.
