The Trouée d’Arenberg, also know as Tranchée d’Arenberg, (Trench of Arenberg), Trouee de Wallers Arenberg, is a straight cobbled road passing through the Arenberg Forest in North France, and highly considered as the most dangerous and toughest part of the Paris-Roubaix. The 2.4 km cobbled road first used in Paris-Roubaix in 1968, and quickly became the race’s symbol. The road was proposed for the “Queen of the Classics” by former professional cyclist Jean Stablinski. Stablinski had a special knowledge of Arenberg. Before he even turned professional he worked in the mine at the southern entrance to the Forest.
