Description
In the 111th edition of La Doyenne (2025), the Col de Haussire returns to the route — for the first time since 1995. Often considered the toughest climb in Belgium, it stretches nearly 4 km, with narrow roads and steep ramps. Positioned among a series of legendary ascents, it adds an extra challenge for the riders. At the summit, they pass the memorial to Claudy Criquielion.
