The seventh All-Africa Games were held in September 1999 in Johannesburg, South Africa. As the track is at an altitude of 1748 metres all performances are considered to be set at altitude, this is believed to assist events up to 400 metres and in the long jump and triple jump. However, for events beyond 800 metres the thinner air is believed to have a detrimental effect on performances. Some new women's events were added: pole vault, hammer throw and 10 kilometres road walk.
