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 entire course. In many countries, athletes previously competed in the 440-yard dash (402.336 m)—which is a quarter of a mile and was referred to as the 'quarter-mile'—instead of the 400 m (437.445 yards), though this distance is now obsolete.
The World Triathlon Championship Series is World Triathlon's annual series of triathlon events used to crown an annual world champion since 2008. There are multiple rounds of competitions culminating in a Grand Final race. Athletes compete head-to-head for points in these races that will determine the overall World Triathlon champion. The elite championship races are held, with one exception, over two distances, the standard or 'Olympic' distance and the sprint distance. The ITU world champion between 1989 and 2008 had been decided in a single annual championship race.
