Muur van Geraardsbergen

From the Dender bridge over the Markt and up through the town, then the cobbled Oudebergstraat to the Kapelmuur, the chapel on the top: 1.1 km at 9.3% with the last ramp at 19.8%. The Muur was the Ronde van Vlaanderen's penultimate climb for decades and is where the race was decided more often than anywhere else; it now sits earlier in the day, and remains the climb the crowd comes for.
