The Brands Hatch 1000 km was an endurance sports car event that was part of the World Sportscar Championship for varying years from 1967 until 1989. Originally a six-hour race running under the name BOAC 500, the event was eventually extended to 1000 kilometres under a number of different sponsorship titles.
In 1966, a non-championship sports car race was held at Brands Hatch for a distance of 500 miles, with drivers David Piper and Bob Bondurant easily taking victory in an AC Cobra. With the success of this initial event, the World Sportscar Championship would add Brands Hatch to their calendar, while the British Sports Car Championship replaced their event. However, unlike the initial race's set distance of 500 miles, the new event would be run for six hours. Even with a timed race, BOAC stepped in as the primary sponsor and chose to retain the 500 mile distance in the name, earning the popular title BOAC 500.
The 1968 race took place on 7 April, a date which will be remembered as that on which Jim Clark, originally expected to take part in the race, instead took part in a Formula 2 race at the Hockenheimring in Germany where he crashed and was killed.
As the speeds of competitors improved during the early years, the drivers would actually set distances beyond even 600 miles. It was therefore decided in 1970 that the event would be extended to a set distance of 1000 kilometres, which was the distance used by five other events in the World Sportscar Championship's calendar. The race, now retitled the BOAC 1000, would continue in this form until it was temporarily dropped from the series in 1973. It would once again be part of the schedule in 1974, but this time with British Airways replacing BOAC as sponsor. The race would however not return again in 1975 and would go on a three-year hiatus.
Following some reconstruction of Brands Hatch in 1976, the World Championship of Makes (split from the World Sportscar Championship) would return to the track in 1977 with a six-hour timed race replacing the 1000 kilometre set distance. The event would skip one more year in 1978, before returning permanently in 1979. The six-hour requirement was abandoned once again in 1981 as the event returned to its familiar 1000 kilometre format, which would continue until 1988. For the final appearance of Brands Hatch on the World Sportscar Championship calendar in 1989, the race would be shortened to 480 kilometres, as would nearly every race that season.
