The Mur de Huy is considered by many to be the toughest climb in the Ardennes and the super-steep ascent decides the winner of La Flèche Wallonne each April.
The clue is in the name. The climb rises out of the town of Huy, while Mur translates to ‘wall’ – The Wall of Huy. The ascent is only short, just 1.2km long, but the gradient peaks at 26 per cent on an S-bend that can bring the peloton to a halt.
Visit the Mur du Huy on race day and it’s transformed from a quiet residential road to a wall of noise, packed with cycling fans with a beer in one hand and frites in the other.
Average gradient: 10 per cent
Start elevation: 122m
End elevation: 242m
