Located in Huy, in the country's Walloon Region and Province of Liege of southern Belgium, the Mur de Huy (The wall of Huy) is one of the steepest, toughest and most spectacular finishing climbs in professional cycling.
The climb starts from Huy at an elevation of 121 m (397 ft) above the sea level. The ascent is only short, just 1,300 m (4,300 ft) long, ending at 204 m (669 ft) above the sea level. The average gradient is 9.3% but the gradient peaks at 26 per cent – more than one-in-four – on an S-bend. Brutal is a word used often in cycling, but there isn’t a better one to describe the Mur.
The surface of the road is paved but narrow. The Mur de Huy is one of the truly definitive climbs. It’s famous for being part of the route of La Flèche Wallonne professional cycling race. It hosted the finish of Flèche Wallonne in 1983, and it debuted in style with victory by Bernard Hinault. The climb is also known as le Chemin des Chapelles (“The Path of the Chapels”) because of the 7 chapels along its route.
