Beyond the definition
A pacer is usually someone or something that keeps or sets a steady speed. In running, a pacer is a runner who helps others stay on target for a certain finish time. In horse racing, a pacer is a horse that moves with a special side-to-side gait called a pace. The word can also mean someone who paces, walking back and forth in a room while thinking, waiting, or feeling nervous.
The word "pacer" is used for a person or animal connected with pace, speed, or repeated back-and-forth movement. One common meaning appears in races, especially long-distance running. There, a pacer is a runner who goes at a planned speed so other runners can follow and reach a goal time. This person may lead a group for part of the race and help keep the effort steady.
Another important meaning is in horse racing and breeding. A pacer is a horse that uses a pacing gait, moving the legs on the same side of the body together. This is different from a trot and is a standard way to describe a certain kind of racehorse.
The word can also be used more literally for someone who paces, meaning they walk back and forth again and again. You might see this in a waiting room, a hallway, or outside during a tense moment. In all of these uses, the idea is steady movement or keeping a certain rate, but the most common meanings are the race helper and the horse.
