What is a moderately fast two-beat lateral gait known as?

The correct answer is a moderately fast two-beat lateral gait known as a pace. This gait, characterized by the simultaneous movement of lateral pairs of legs (i.e., the two legs on the same side move together), is distinct from other gaits.

The pace is often utilized by harness racing horses and is one of the basic gaits in equine movement. Unlike the trot, which has a diagonal two-beat rhythm (opposite legs moving together), the pace maintains a lateral two-beat rhythm. This gait allows for efficient forward movement, particularly in certain racing contexts.

Understanding this helps clarify why the pace is specifically noted for its lateral movement and moderate speed, which distinguishes it from slower gaits such as the walk or more complex gaits such as the gallop. The trot is a diagonal gait and should not be confused with the pace due to the difference in leg movement.
