Since 1977, the Paris-Roubaix has no longer started from the capital, as its name suggests, but from Compiègne. The course then travels nearly 250 kilometres north, crossing 27 cobblestone sections (nearly 50 km of discomfort in total). One of the most well known in the Paris-Roubaix is the infamous ‘Trouée d’Arenberg’ - 2 km long and rated grade 5* in difficulty. It often causes the first falls among the peloton or breakaway groups. Further on, at ‘Le Carrefour de l’Arbre’ cobblestone section in Gruson, it is often said that any competitor leading at that point has a high chance of winning. The atmosphere and excitement are therefore at their height...Then it's on to the Roubaix Velodrome, where the victor will have justly deserved the chance the lift the cobblestone trophy!
