How do you teach a horse to respond to the rate cue on the flat before introducing it at the barrel?

Teaching the rate cue begins entirely on the flat, away from the barrel pattern, so the horse learns the response as a simple communication before it is asked to apply it in the more complex context of a turn at speed. The rate cue most commonly used in barrel racing combines a slight deepening of the rider's seat, a soft increase in rein contact, and in many cases a verbal cue such as a cluck or the word whoa said quietly. The specific components of the cue vary by rider and horse, but the principle is the same — a clear, consistent signal that means collect your stride and shift your weight back. On the flat at a working lope, the rider applies the rate cue and waits for the horse to respond by shortening its stride and softening through its back. When the horse responds correctly, even slightly, the cue is immediately released and the horse is allowed to move forward again. This release — the reward for the correct response — is the most important part of the exercise. Horses learn the rate cue through the pattern of cue, response, and release repeated consistently over many sessions. The cue should be kept as light as possible from the beginning. Starting with the lightest possible aid and adding pressure only if the horse does not respond teaches the horse to listen for the subtle version of the cue rather than waiting for strong pressure. Once the horse responds reliably to a light rate cue at a working lope on the flat, the same cue is introduced on the approach to a barrel at a slow pace before any speed is added.
