The proper length of the first lane of a competitive running track is 400 m (1,312.3 ft). Some tracks are not built to this specification, instead being a legacy to imperial distances such as 440 yd (402.336 m), equivalent to a quarter of a mile.
The 110 metres hurdles, or 110-metre hurdles, is a hurdling track and field event for men. It is included in the athletics programme at the Summer Olympic Games. The female counterpart is the 100 metres hurdles. As part of a racing event, ten hurdles of 42 inches (106.7 cm) in height are evenly spaced along a straight course of 110 metres. They ...

See Category:Standard gauge railways: Standard gauge is defined both in metric and in imperial units. It is also the best-known gauge worldwide; 55% of the world uses this track. In 2020, China’s rail network is standard gauge, with around 79,685 km (49,514 mi) of line. [92] 1,440 mm 4 ft 8 + 11 ⁄ 16 in: Switzerland
The measurement of uniformity is done using a predefined length of string line (normally the same length used in horizontal alignment) along the track. If the midpoint of the measurement has higher elevation, it is called hump deviation. On the other hand, if the midpoint has lower elevation, it is called dip deviation. [9]
The 1928 games were also the first games to use a 400-meter track, which became the standard for track and field. The modern sprinting events have their roots in races of imperial measurements which were later altered to metric: the 100 m evolved from the 100-yard dash , [ 7 ] the 200 m distance came from the furlong (or 1 ⁄ 8 mile ), [ 8 ...
The two basic features of a track and field stadium are the outer oval-shaped running track and an area of turf within this track—the field. In earlier competitions, track lengths varied: the Panathinaiko Stadium measured 333.33 metres at the 1896 Summer Olympics , while at the 1904 Olympics the distance was a third of a mile (536.45 m) at ...
The 400 metres, or 400-meter dash, is a sprint event in track and field competitions. It has been featured in the athletics programme at the Summer Olympics since 1896 for men and since 1964 for women. On a standard outdoor running track, it is one lap around the track. Runners start in staggered positions and race in separate lanes for the ...
