The hill is best known from cycling, where it regularly features the Flemish races in spring, most notably the Tour of Flanders. The uphill slopes of the Kortekeer start gently before steadily getting tougher as it winds its way through the woods. The asphalt is fairly smooth, but is usually covered in mud and gravel from the high banks. Despite its central location in the Flemish Ardennes, it is a relatively new climb in cycling races. It was first included in the Tour of Flanders in 1988, as a replacement for the nearby Koppenberg, which was deemed too dangerous for a peloton to climb. It has however never become a fixed site of the race.
