 The ACO, having previous helped in the creation of the American Le Mans Series with the running of the 1998 Petit Le Mans, as well as a failed attempt at a Japanese sportscar series with the 1999 Le Mans Fuji 1000km, created the 1000 km of Le Mans as an experimental event to gauge the desire for teams to participate in a European-based endurance sportscar series under Le Mans rules.Previously, the FIA Sportscar and FIA GT Championships had run primarily in Europe, but were not running as a combined series, one concentrating on prototypes and the other grand tourers, and featured mostly sprint or middle-distance races.Don Panoz, creator of the American Le Mans Series, had attempted to create a European series to combine the two types of sportscars with the European Le Mans Series, but had failed to gain enough entrants.
