Javelin model

The javelin throw is a track and field event where the javelin, a spear about 2.5 m (8 ft 2 in) in length, is thrown. The javelin thrower gains momentum by running within a predetermined area. Javelin throwing is an event of both the men's decathlon and the women's heptathlon.

The javelin was part of the pentathlon of the Ancient Olympic Games beginning in 708 BC in two disciplines, distance and target throw. The javelin was thrown with the aid of a thong, called ankyle wound around the middle of the shaft. Athletes would hold the javelin by the thong and when the javelin was released this thong unwound giving the javelin a spiraled flight.

Throwing javelin-like poles into targets was revived in Germany and Sweden in the early 1870s. In Sweden, these poles developed into the modern javelin, and throwing them for distance became a common event there and in Finland in the 1880s. The rules continued to evolve over the next decades; originally, javelins were thrown with no run-up, and holding them by the grip at the center of gravity was not always mandatory. Limited run-ups were introduced in the late 1890s, and soon developed into the modern unlimited run-up.

Sweden's Eric Lemming, who threw his first world best (49.32 meters) in 1899 and ruled the event from 1902 to 1912, was the first dominant javelin thrower. When the men's javelin was introduced as an Olympic discipline at the 1906 Intercalated Games, Lemming won by almost nine metres and broke his own world record; Sweden swept the first four places, as Finland's best throwers were absent and the event had yet to become popular in any other country. Though challenged by younger talents, Lemming repeated as Olympic champion in 1908 and 1912; his eventual best mark (62.32 m, thrown after the 1912 Olympics) was the first javelin world record to be officially ratified by the International Association of Athletics Federations.
