ECURIE 41

Ecurie 41 is a motorsport association based in Lassay-sur-Croisne in the Loir-et-Cher department. The association was founded in 1980 through the merger of the Écuries 'Blésoise' and 'Denis Papin' and is considered the oldest motorsport association in the department.

Since its founding, Écurie 41 has organized the Course de Côte de Fréteval and the Rallye de la Vallée du Cher, both listed on the calendar of the French motorsport federation. Since 2011, a rally for historic vehicles (V.H.C.) has been held alongside the Rallye de la Vallée du Cher, and since 2012 the Rallye Historique du Loir-et-Cher, a regularity rally on open roads held each year in a different area of the department. The hill climb category in Fréteval has also included historic vehicle classes for several years.

The club counts around 80 members each year, including drivers, co-drivers, marshals and volunteers passionate about motorsport in all its disciplines.
