The 2013 Le Mans 24 Hours has been moved back one week “at the request of the Fédération Internationale de l’Automobile (FIA) in order to harmonise the world calendar of motor racing events”. Hopefully that means no F1 clash again!
The race will take place on June 22nd-23rd. It will be its 81st running and the 90th anniversary of the first race. The test will be on Sunday 9th June.
