Six riders – Eddy Merckx, Roger De Vlaeminck, Freddy Maertens, André Dierickx, Dietrich Thurau and Bernard Hinault – were in front of the race. While all eyes were on Eddy Merckx, André Dierickx launched an attack at 8 km from the finish. Frenchman Bernard Hinault was the only one to respond and beat Dierickx in the sprint. A faltering Merckx, in his final display in Liège, finished a disappointing sixth.
The race was run in bad weather, with cold and rain affecting riders. Only 24 of 143 riders finished the race.
