Queen of the Classics, Hell of the North, A Sunday in Hell… the pavé of Paris-Roubaix takes centre-stage on Sunday (April 10) with 52.8km of cobblestones packed into the 257.5km course.
Organisers ASO have rated the secteurs according to their difficulty, with the iconic Arenberg Forest, Mons-en-Pévèle and Carrefour de l’Arbre all ranked five out of five for toughness.
But they are just three of the 27 stretches of brutal pavé the peloton must tackle on Sunday, and the team at Strava have taken a closer look at the 12 key secteurs.
Just how tough are they? How fast do the pros ride them? And how do you compare?
