The race was run over two days with the drivers completing ten laps on each day and their times being aggregated to produce the winner (similar to a modern rally race).

[1] Riding mechanic Jean Bassignano was killed in a lap 3 crash when his driver Léon Collinet put a wheel off and flipped.

Victor Hémery, driving a Lorraine-Dietrich, was the first to complete a lap, but David Bruce-Brown's Fiat led on time after lap one and retained the lead overnight, more than two minutes ahead of Georges Boillot's Peugeot.

During the second day, Bruce-Brown was disqualified for refuelling away from the pits on lap 15, giving Boillot a comfortable victory by over thirteen minutes from Wagner.

[2] The Sunbeams performed extremely well in the Coupe de l'Auto race, with Rigal finishing in first place, Resta second, and Medinger third.
