The 800 metres, or meters, is a common track running event. It is the shortest commonly run middle-distance running event. The 800 metres is run over two laps of an outdoor (400-metre) track and has been an Olympic event since the first modern games in 1896. During the winter track season the event is usually run by completing four laps of an indoor 200-metre track.
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.
Sex verification in sports occurs because eligibility of athletes to compete is restricted whenever sporting events are limited to a single sex, which is generally the case, as well as when events are limited to mixed-sex teams of defined composition. Practice has varied tremendously over time, across borders and by competitive level. Issues have arisen multiple times in the Olympic games and other high-profile sporting competitions, for example allegations that certain male athletes attempted to compete as women or that certain female athletes had intersex conditions perceived to give unfair advantage. The topic of sex verification is related to the more recent question of how to treat transgender people in sports. Sex verification is not typically conducted on athletes competing in the male category because there is generally no perceived competitive advantage for a female or intersex athlete to compete in male categories.

The Olympic Games mandates sex verification of athletes in women's competitions, and has done since the 1930s. In this time, there have been many different regulations for sex testing, as well as different types of tests used. Initial concerns that prompted the approval of suspicion-based sex testing were of national teams exploiting intersex athletes for Olympic success, and testing first became a requirement in the 1960s when many female athletes were doped and it was harder to tell physical differences between them and men.
