The new date meant that the Italian teams were unable to attend, leaving it to be mostly an internal French affair with sixteen Bugattis, two Peugeots and a Delage among the twenty five starters.

Among the top Bugatti drivers were Louis Chiron, Marcel Lehoux, Count Stanislas Czaikowski, Jean-Pierre Wimille, Philippe Étancelin and William Grover-Williams.

A curiosity in the largely single-seat entry list was Tim Birkin's 4½-litre supercharged "Blower Bentley" touring car, stripped down to racing trim, with headlights and mudguards removed.

Guy Bouriat took an early lead, followed by Williams, Zanelli, Czaikowski and Étancelin, with Birkin as first non-Bugatti driver, in sixth place.

The Bentley driver used his horn to warn the Bugatti to move over, surely a unique occurrence in Grand Prix racing!
