Paris-Roubaix — the Hell of the North — returns this Sunday, April 12. It is cycling’s most brutal one-day classic: 260 kilometres from Compiègne to Roubaix, punctuated by 55 cobblestone sectors totalling around 54 kilometres of paved medieval farm tracks that have shattered dreams, careers and bicycles for over a century.
This year’s race carries extraordinary storylines. Mathieu van der Poel seeks a record-equalling fourth Roubaix title. Tadej Pogačar — who won Tour of Flanders — chases an unprecedented Spring Classics sweep. And the women’s race on Saturday features arguably the deepest field in the event’s short but spectacular history. Our full preview of the men’s race covers the favourites and race dynamics in detail.
But to truly appreciate Paris-Roubaix — whether you’re watching from a cafe, trackside or a velodrome seat — you need to understand the cobbled sectors themselves. This is your complete guide.
How the Sectors Work
Each cobbled sector is rated from one to five stars by the race organisation. Five stars is the most brutal — the sectors that have historically decided the race. One-star sectors are rough enough to be damaging but rarely race-decisive on their own.
The sectors are numbered in reverse order of their appearance on the route — sector 29 is the first you’ll encounter, sector 1 is the final cobbled passage before the velodrome. This somewhat counterintuitive numbering is a quirk of Roubaix tradition.
The race is broadly divided into three phases: the opening flat roads to the first cobbles (where breakaways form), the middle phase through the sectors (where selection happens), and the finale into Roubaix (where champions are made).
The Sectors That Will Decide the Race
Trouée d’Arenberg (Sector 18) — ★★★★★
The most famous cobbled sector in cycling. 2,300 metres through a forest cutting, with ancient stones that have settled at every angle imaginable. Riders enter at speed through a narrow forest lane, then navigate 2.3 kilometres of pure attrition. Punctures, crashes and mechanical failures here have ended countless title bids. The Arenberg is typically raced around kilometre 160, when riders have already accumulated significant fatigue.
Mons-en-Pévèle (Sector 11) — ★★★★★
Coming approximately 30 kilometres after Arenberg, this 3,000-metre sector is one of the longest in the race. By this point, survival instinct kicks in — the peloton has usually splintered, and it’s a battle between whatever groups have formed. Strong riders who can maintain momentum through this sector often find themselves in the decisive move.
Carrefour de l’Arbre (Sector 4) — ★★★★★
With just 17 kilometres remaining after it ends, this is the last truly decisive sector. Coming after hours of accumulated cobbled punishment, the 2,100 metres of Carrefour are where the final selection happens. Whoever is on the front group after Carrefour has a genuine chance of victory.
Camphin-en-Pévèle (Sector 5) — ★★★★
Immediately follows Carrefour de l’Arbre and confirms the decisive nature of that final passage. At four stars, it’s rough enough to further shred the final group and often sends lone attackers clear toward Roubaix.
Watching Tips for Sunday
If you’re watching on television or streaming, here are the times and moments to stay fixed to your screen:
First 100km: Largely processional. Breakaways form, teams play cat and mouse. Worth following loosely but the real race hasn’t started. The first cobbled sectors (around km 100) will give you an early read on who is moving well and who might be conserving.
Mons-en-Pévèle through Carrefour de l’Arbre (final 50km): This is the race. Don’t look away. Every gear change, every wheel-touch, every attempted acceleration is meaningful. The final decisive move — whether it’s a solo attack or a small group going clear — almost always happens in this stretch.
The velodrome: If two or more riders arrive together, the sprint in the Roubaix velodrome is one of sport’s most dramatic finishes. The steep banking, the roaring crowd, and the knowledge that the winner will join a century of legends makes it unmissable.
The Women’s Race: Saturday April 11
The Paris-Roubaix Femmes Hauts-de-France — now firmly established as one of the Women’s WorldTour’s most prestigious events — races on Saturday. Our women’s race preview covers the key contenders, with Lotte Kopecky and Demi Vollering (fresh from her Tour of Flanders win) the pre-race favourites.
The women’s race covers a shorter but equally demanding cobbled course. The racing is consistently aggressive and the quality of the field has reached a level where any team strategy error results in elimination from contention.
How to Prepare Your Riding for Cobbles
Many cyclists who watch Paris-Roubaix are inspired to seek out their own cobblestone adventures. If you’re planning a gravel or cobbled ride, preparation matters significantly more than it does on smooth tarmac. Our gravel and rough-road race preparation guide covers the setup, training and fuelling elements that make rough-terrain riding sustainable and enjoyable.
The professionals running Paris-Roubaix use tyres at pressures as low as 3-4 bar and run tubulars or tubeless specifically designed for cobblestones. The principle — lower pressure for compliance and shock absorption — applies equally to amateur gravel and cobble riding.
Key Takeaways

- The three decisive sectors are Trouée d’Arenberg (★★★★★), Mons-en-Pévèle (★★★★★), and Carrefour de l’Arbre (★★★★★).
- Watch the Arenberg for the first major selection; stay glued from Mons-en-Pévèle through Carrefour for the final drama.
- Van der Poel seeks a record-equalling fourth title; Pogačar aims for an unprecedented Spring Classics double.
- The velodrome finish, if it comes to a sprint, is one of sport’s greatest spectacles.
Paris-Roubaix is not just a bike race. It is a test of machine, man and will against terrain that has remained fundamentally unchanged for a century. Clear your Sunday — this one demands your full attention.
