Equestrian

The only Olympic sport where human and animal compete as one, Equestrian features Dressage ("horse ballet" with imperceptible signals), Jumping (clearing 1.6m fences without knocking a rail), and Eventing (an equestrian triathlon: dressage, cross-country, jumping). The horse's ears flick back to listen to the rider, then forward to focus on the jump, and the most dramatic moment is a refusal (the horse stops at a fence) or a runout, making it a silent conversation at high speed.
