In many forms of racing, a straight or stretch is a part of the race track in which the competitors travel in a straight line for any significant time, as opposed to a bend or curve. The term is used in horse racing, motor racing and track and field athletics.
In athletics, a typical 400 m track features two straights and two bends. The final straight before the finish line is known as the home straight, or the pit straight in Formula One, while the other is known as the back straight.
In motor racing, both the pit lane and finish line are often located on the longest straight on the circuit. Notable exceptions are the 6 km Mulsanne Straight at Le Mans, which is at the opposite side of the circuit; and at the Silverstone Circuit, which has the pit lane on the Hamilton Straight, rather than the Hangar Straight.
In the United States the home straight in athletics, and also the straight part of a motor racing track, is sometimes referred to as a straightaway. The final straight is sometimes known as the home stretch.
A velodrome is an arena for track cycling. Modern velodromes feature steeply banked oval tracks, consisting of two 180-degree circular bends connected by two straights. The straights transition to the circular turn through a moderate easement curve.
A race track is a facility built for racing of vehicles, athletes, or animals. A race track also may feature grandstands or concourses. Race tracks are also used in the study of animal locomotion.

Oval track racing is a form of closed-circuit motorsport that is contested on an oval-shaped race track. An oval track differs from a road course in that the layout resembles an oval with turns in only one direction, and the direction of traffic is almost universally counter-clockwise. Oval tracks are dedicated motorsport circuits, used predominantly in the United States. They often have banked turns and some, despite the name, are not precisely oval, and the shape of the track can vary.

Racing flags are traditionally used in auto racing and similar motorsports to indicate track conditions and to communicate important messages to drivers. Typically, the starter, sometimes the grand marshal of a race, waves the flags atop a flag stand near the start/finish line. Track marshals are also stationed at observation posts along the race track in order to communicate both local and course-wide conditions to drivers. Alternatively, some race tracks employ lights to supplement the primary flag at the start/finish line.
