The Automobile Club de l'Ouest has announced the date for the 77th running of the Le Mans 24 Hours.
The biggest event on the sportscar calendar will run on the weekend of 13/14 June 2009 and will be the first edition of the 24 hour classic to run under a new set of regulations that will be brought into play bit-by-bit between now and 2011.
The new Formula Le Mans series, created by the ACO and Oreca will hold a round of its maiden season at the 24 Hours as a curtain raiser to the main event.
The traditional pre-event test day for the 55 entrants selected by the ACO for the race will take place on 31 May, where teams will get seven hours of track time as they finalise their preparations for the event.
As well as the Le Mans 24 Hours itself, La Sarthe will also play host to a two-day test session for the teams contesting the 2009 Le Mans Series season.
The test, slated to take place on 22/23 April on the Bugatti Circuit, will come between the opening race of the season at Catalunya and the second round at Spa.
The calendar for the Le Mans Series will again feature five races, although Monza – which saw a number of high-speed accidents that involved prototype cars getting airbourne – will not feature and is replaced by a race at the new Algarve circuit in Portugal.
