When a rider with Down syndrome starts lessons, what is a basic skill they need to master for a trail ride?

The correct choice focuses on the foundational skills necessary for a rider embarking on trail riding, particularly for individuals with Down syndrome. Mastering the ability to have the horse walk on is crucial as walking is the basic gait and serves as the starting point for all riding activities.

Establishing comfort and control at the walking pace allows the rider to build confidence and develop an understanding of how to interact with the horse. Once the rider is secure and proficient at having the horse walk, they can more effectively transition to other skills that involve more complex maneuvers, such as trotting or controlling the horse's speed. Additionally, ensuring that the horse walks promptly provides a safer and more manageable experience, especially for beginners or those who may require more time to process instructions. This foundational skill is vital before progressing to more advanced techniques like steering or manipulating speed, which depend heavily on the comfort and familiarity established during the walking phase.
