Koppenberg (literally "Heads Mountain") is a 77 m (253 ft) high hill in Oudenaarde, the Flemish Ardennes, Belgium. "Koppen" is an abbreviation for cobblestones which in Dutch slang language are called kinderkoppen, or "children's heads". This climb is part of the route of the Tour of Flanders professional cycling race and feared by many because of its steepness (22% on the trickiest parts) and because of its cobblestones. This makes the Koppenberg difficult even for top professionals. Quite often, riders slow to the point of losing their balance, especially those at the back of the peloton who have to dismount and scramble to the top on foot.
Strategically, the climb has little importance: it's too far from the finish (in 2006, on km 185 of 259). Even if a breakaway forms on the Koppenberg it is difficult for riders to hold off the peloton in the finishing stages. In the 2012 course change the Koppenberg is moved to 60 km from the finishline and can be more decisive in the Ronde than in the old course.
Koppenberg was first climbed by the Tour of Flanders riders in 1976 and featured annually until 1987.
In that year, Danish rider Jesper Skibby broke away from the peloton early in the race and had been riding by himself when he approached the Koppenberg. With a lead of nearly two minutes, he began the climb but fell. The race commissaire, in his car, could not wait because the peloton was approaching. He ordered his driver to move and the car passed over Skibby's front wheel, destroying it but avoiding Skibby, while the rider and his bike were still lying on the cobblestones.
After the incident, the Koppenberg was excluded for 15 years. After renovations, which included widening the road and re-paving it, the climb was re-introduced in 2002.
The Koppenberg was again excluded from the Tour of Flanders because of its deteriorating and unsafe conditions in 2007. Following further renovations that year, it was again included in the 2008 edition of the race, and has been featured in each edition since.
The Koppenberg hillside is also used for the annual Cyclo-cross Koppenberg race. The cyclo-cross course follows only part of the cobbled road, using some of the surrounding fields and roads for the other sections of the course.
