stages of the race to make a break. In modern cycling, as in many bike races, the decisive stretches have evolved towards the final climbs of the day. The Côte de Saint-Nicolas is the last categorized climb of the race, with the top at 6 km from the finish in Ans. It is a precipitous and atypical climb because it is not part of the forested hills in the Ardennes, but located in the middle of the industrial suburbs of Liège along the Meuse river. In 2016, the organisers inserted the 600 m cobbled Côte de la Rue Naniot following the Côte de Saint-Nicolas, but preceding the finish in Ans. This turned out to be a one-off, however, as the race has not used the climb since. Since the finish returned to Liège in 2019, the Côte de Saint-Nicolas has been removed from the route, and the decisive climbs are once again the Côte de la Redoute, Côte des Forges and Côte de la Roche-aux-Faucons. Course changes are frequent from year to year. Climbs are sometimes cut or others included.

The edition of 1980 was exceptionally hard: snow fell from the start and temperatures were near freezing point, leading commentators to call it 'Neige-Bastogne-Neige' (Snow-Bastogne-Snow). Bernard Hinault attacked with to go and finished nearly 10 minutes ahead. A feature published by the British magazine, Procycling in 2000, described the infamous race: A cold wind that blew across Belgium brought snow flakes and then a heavy fall within moments of the race starting. (...) Riders struggled on, with hands to faces to keep a view of the road. The race was an anonymous mass of plastic jackets and windcheaters. Spectators stood in goggles like upmarket snowmen, red-faced in the bitterness. Within the hour some teams had barely a man left on the road. They pulled out two dozen at a time, men like Gibi Baronchelli and Giuseppe Saronni, Lucien Van Impe and Jean-René Bernaudeau. Bernard Hinault, the winner, was one of just 21 riders to finish the race of 174 starters. It took three weeks for proper movement to return to two fingers of his right hand.
