Three of the 30 cobbled sectors on the program, the Arenberg gap, Mons-en-Pévèle and the Carrefour de l'Arbre, are rated at the highest as being the most difficult of the classic Paris-Roubaix cycle scheduled for Sunday.
The 30 sectors of the “queen of classics” represent a total length of 55 kilometers.
They are numbered in descending order with respect to the arrival at the northern velodrome.
The rating varies from 1 to 5 (from the least difficult to the most difficult), following a color code (green, blue, orange, red, black), taking into account the condition of the paving stones, the length of the sector and its position in the race.
