Equipped for Racing
Every piece of equipment used on
a Standardbred has been selected
specifically for that horse’s individual
needs. This guide will explain the
purpose of the most commonly used
equipment.

1. Racebike
Also known as a sulky, an aerodynamic cart used only
in races, which reduces drag and provides lift on the
horse.
2. Driving lines
Straps attached to the driving bit that run back to
the handholds, which the driver uses to control the
direction and speed of the horse.
3. Harness
Holds the equipment in position on the horse, and
consists of the bridle, saddle, girth and crupper. The
girth connects the harness around the belly. The
crupper is a loop that slides under the base of the tail
to keep the harness from moving forward.
4. Head Number
Connects to the crown of the bridle and designates the
horse’s number in the racing program.
5. Bridle
Consists of several straps, usually leather, that fit over
the head and face of the horse, allowing the driver to
control the horse through the use of a driving bit. The
blind bridle shown here obscures sight from the sides
as well as from behind, which prevents the horse from
seeing anything that may cause anxiety.
6. Driving bit
Usually a jointed metal bar seated in an area of the
horse’s mouth between the front incisors and molars,
where there are no teeth. By creating
pressure on the sides of the mouth
through the driving lines, the
driver can steer the horse.
7. Headpole
Runs along the head and neck and hooks to the harness
to keep the horse from turning its head, which may
cause it to break stride.
8. Bell boots
Rubber hoof covers used to protect a horse from hitting
its front heels with its rear hoof.
9. Shin boots
Worn on the hind legs just beneath the hock and over
the ankle, covering the hind legs to provide additional
protection from getting struck with a hoof.

10. Open bridle
Allows the horse a full range of sight with
no obstruction. Open bridles are useful
to relax an otherwise tense or aggressive
animal.
11. Overcheck
A rein generally attached to the overcheck
bit, running over the top of the head and
down the neck where it is strapped to the
harness. It prevents the horse from lowering
its head, which helps maintain a proper gait.
12. Saddle pad
Designates the horse’s program number in the race.
Each numbered saddle pad corresponds to a particular
color. The smaller number is the race number.
13. Tail tie
When a horse wants to swish his tail, it is generally a
sign that it is going to kick. A tie may be used to brace
the tail from movement, which helps the horse resist the
urge to kick.
14. Jog cart
Used for training, it is heavier than a race bike and is
more comfortable for the driver. Many horses warming
up between races will also be seen pulling a jog cart.
15. Hobbles
Also called hopples, plastic loops worn by pacers to
help the horse maintain the pacing gait. Hobbles for
trotters are similar to pacing hobbles, but the loops are
worn only around the front legs, and are joined by a
rope and pulley that hangs underneath the horse.
16. Tendon boots
Used to protect the tendon of the front foreleg between
the knee joint and the ankle from being struck by a
hoof on the opposite foreleg.
17. Knee boots
Worn on the forelegs to protect from knee-knocking,
which occurs when the knee is struck by the hoof of the
opposite leg.
18. Knee spreaders
Used to widen the horse’s gait in its front legs to
prevent it from hitting its knees.
19. Buxton
Nylon strap that runs across the shoulders, around the
neck and between the front legs in a Y-shape, which
prevents the harness from slipping backward.
