A Pacer Standardbred is a Standardbred who is capable of pacing, and competes in harness races where pacing is allowed.

What is 'pace'?:
The pace is a 2-beat gait, where the horse moves their legs in the following sequence: hind-right together with front-right, followed by hind-left together with front-left.

In Standardbreds, there is always a suspension phase where all of the four legs are in the air. The pacing of Pacer Standardbreds is incredibly fast, and can have the speed of a canter.

The Pacer Standardbred:
The need for Standardbreds who can pace fast for long durations of time led to the creation of a subgroup within the Standardbred breed, called "Pacer Standardbreds." Standardbreds in this group excel in pacing, and often pass their ability to pace to their offspring. As such, Pacer Standardbreds have their own bloodlines, and breeders usually avoid crossing Non-Pacer Standardbreds with Pacer ones.

Gaits:
Pacer Standardbreds are capable of both trot and pace, but they are trained to maintain their pace when in harness, and to not break into a trot.

In Horse Isle, any Standardbred who can pace is classified as a "Pacer Standardbred" regardless of their ability to trot. As such, gaited standardbreds also fall under this classification because, despite having an ambling gait instead of a trot, they always pace.

Performance metrics:
The following are the: range, average, (SD), and MOE of performance metrics of ordered Standardbreds in Horse Isle (not bred ones). In rare cases, horses might have metrics outside of the range. Breeders can produce horses that are beyond this range.

Sprint: 57-69, 63 (3), 0.54.

Accel: 0.87-1.07, 0.97 (0.04), 0.01.
