This climb is merciless, one mistake can be fatal
Situated in Belgium it feels like hitting a cobblestoned wall. It’s a cobbled stone road 600 meters in length with grueling stretches of 22%. One of the steepest hills in Belgium with a bad, very uneven cobbled surface. Its road is also extremely narrow and the high banking on either side turns it into a natural arena. T shirts with the text ‘’I did the Koppenberg’’ are being sold, afterwards you will know why.
