A race to cover a certain distance may be any length, and using any means stipulated by the rules. Running a distance is the most basic form of racing, but races are often conducted in vehicles, such as boats and cars, on or with animals such as horses and in aircraft.
A race may be run continuously from start to finish or may be made of several segments called heats or stages. A heat is usually run over the same course at different times. A stage is a shorter section of a much longer course or a time trial.
Early records of races are evident on pottery from ancient Greece, which depicted running men vying for first place. A chariot race is described in Homer's Iliad.
The word race comes from a Viking word. This Viking word arrived in France during the invading of Normandy and gave the word raz which means "swift water" in Brittany; it can be found in "Pointe du Raz" (the most western point of France, in Brittany), and "raz-de-marée" (tsunami).
A race and its name are often associated with the place of origin, the means of transport and the distance of the race. As a couple of examples, see the Dakar Rally or the Athens marathon.
