Reims-Gueux was first established in 1926 on the public roads between the small French villages of Thillois and Gueux. The circuit had two very long straights between the towns, and teams strove to maximize straight-line speed of their cars; many slipstream battles ensued. Race organizers actually felled trees and demolished old houses in order to make the circuit even quicker.
Its first event was the Grand Prix de la Marne, staged by the Automobile Club of Champagne. International racing came soon thereafter, with the first official Formula One event occurring in 1950, the inaugural year of the Formula One world championship. The circuit layout was shortened and changed in 1952 to bypass the town of Gueux; and the circuit was then renamed Reims. The layout was changed yet again in 1953, it was made slightly longer and faster; two fast curves and a hairpin further up the RN31 highway were added. The circuit was last used by Formula One in 1966 and the last car meeting was held in 1969. Motor bike racing continued for 3 more years and it closed permanently in 1972 due to financial difficulties.
In 1997, there was to be a historic race held there, but for technical reasons, it was cancelled several months before it was due to take place and in 2002, the bulldozers arrived to demolish some portions of the track. Sections of the track around the pit lanes are still visible today.
The old RN31 straight between Muizon and Thillois has been widened and turned into a dual carriageway though it does follow the same line as the original 2 lane road that was raced on. It's still possible to drive a lap around the version of the circuit used until 1952 (though the old Garenne T-junction was obliterated as part of the widening of the RN31). It is no longer possible to complete a lap of the circuit used from 1953 onwards as the tarmac between Bretelle Nord and Muizon has been dug up. The annual historic meeting uses the Circuit d'Essais which came into being in 1952 and uses the 1953 circuit until La Hovette then turns onto the pre-1953 circuit up to Garenne.
Les Amis du Circuit de Gueux is a non-profit organisation working to preserve traces of the circuit.
The lap record of the original circuit (1926–1951) was 2:27.8 by Juan Manuel Fangio in an Alfa Romeo 159, and the lap record for the faster circuit (1954–1972) was 2:11.3 by Lorenzo Bandini in a Ferrari.
