The most controversial and feared climb in professional cycling — banned from the Tour of Flanders in 1988 after Jesper Skibby fell and officials riding motorbikes nearly ran over him, and finally reinstated in 2002. The Koppenberg rises 71m in just 600m of entirely cobbled road, peaking at 22% on sections so steep that even WorldTour professionals regularly struggle to maintain forward momentum on wet race days. The cobbles are among the most irregular on any Flemish berg — large, rounded stones that provide virtually no grip under power. For amateur cyclists, the Koppenberg is frequently walked rather than ridden, but the attempt is obligatory for anyone serious about experiencing Flanders cycling. The narrow, sunken road gives the climb a claustrophobic intensity that amplifies the effort.
Pro Tip
The key to riding the Koppenberg cleanly is committing to a higher gear than feels natural and maintaining absolute pedalling momentum — any break in cadence on 20%+ cobbles is almost impossible to recover from. Pick a dry, warm day for your first attempt. The pub at the top serves well-earned Tripel Karmeliet.
