Boigneberg is a 1.4 km cycling climb averaging 4.1% (+57 m), rising from 29 m to 85 m in Flanders.
Seven Rondes between 1978 and 2007, always the connective tissue between the Eikenberg and Het Foreest, and a regular in E3. Riders take it today as the pavé-free way into the Flemish Ardennes: old concrete slabs that run badly enough to make the hill harder than its average suggests.

What it’s like to ride
Boigneberg climbs out of the Maarkebeek valley on a narrow concrete road and tops out on the N8. It was a poor, narrow cobbled lane when the Ronde van Vlaanderen first used it in 1978 and was concreted the year after, so what you ride now is old slabs, and riders say those slabs run badly enough to make the hill harder than its modest average suggests. The start is where the work is, the steepest hundred metres averaging around 11%, and once that is behind you it opens into a long false flat to the top, the place to empty the tank if you held something back at the bottom. Traffic is close to nothing and the surroundings are good, which is why riders who want the Flemish Ardennes without pavé take this one instead of the Eikenberg just to the west. The Ronde used it seven times (1978, then 2002 to 2007, in the later years always between the Eikenberg and Het Foreest), and it turns up regularly in E3.
