It was the first major race to run on a closed course instead of from one city to another.
[1] The first race, held in 1902, was organised by Baron Pierre de Crawhez, and was run over 6 laps of the circuit, with cars divided into three classes which ran simultaneously.
The Heavy car class was won by Charles Jarrott in one of several Panhard 70s entered in the race, with victory in the Light car going to Louis Rigolly in a Gobron-Brillié, and in the Voiturette class to Jean-Marie Corre in a Corre.
The Heavy car class ran on the morning of 22 June, with the Light car class in the afternoon, and the Voiturettes the following day on a separate circuit based around Arlon.
[4] For the final year of the Circuit des Ardennes two races were again held.
