A Tour of the Five Monument Classics: The Historical Status of Milan-San Remo, Tour of Flanders, Paris-Roubaix, Liège-Bastogne-Liège, and Il Lombardia

What Are “Monument” Level Races

In the world of cycling, “Monument” is an unofficial but widely used designation that specifically describes five one-day classics with the longest history, the highest difficulty, and the greatest esteem among riders and fans. These five races are: Milan-Sanremo, Tour of Flanders (Ronde van Vlaanderen), Paris-Roubaix, Liège-Bastogne-Liège, and Il Lombardia. Most of these five races were founded between the late 19th and early 20th centuries, with histories far longer than many people imagine, and each features unique terrain characteristics and challenges, giving them a status in the eyes of professional riders that rivals—or even surpasses—a single stage win in a three-week stage race like the Tour de France.

Unlike the Tour de France, which requires three consecutive weeks and relies on team tactics and energy management to win overall, Monument races are all “winner-takes-all” one-day events—riders must contend with a single stage ranging from just over 200 kilometers to nearly 300 kilometers, simultaneously managing long-distance energy expenditure, complex and varied terrain challenges, and extremely high-intensity tactical battles in the final phase. This “one shot” race format makes Monument races often more dramatic than stage races, and imposes even stricter demands on riders’ on-the-spot decision-making and ability to perform under pressure.

Below, we introduce the terrain characteristics and historical status of each of the five Monument races in season order.

Milan-Sanremo: The First Test of Spring

Race Characteristics: Long and Flat, Yet Full of Hidden Dangers

Milan-Sanremo is the earliest Monument race of the season and is generally regarded as the benchmark event marking the official start of the Northern Hemisphere cycling season. Most sources indicate that this race was founded in the early 20th century, with a route starting from Milan in northern Italy and heading south to Sanremo on the Mediterranean coast. The total distance ranks among the longest of the five Monuments, and the route is predominantly flat and rolling terrain, lacking the dramatic terrain obstacles found in the Tour of Flanders or Paris-Roubaix.

At first glance, Milan-Sanremo’s terrain may seem relatively “benign,” but precisely because the race distance is extremely long, riders must still contend with several crucial short, steep climbs and descents near the end of the race after riding for over 200 kilometers. The attacks and counter-attacks on these sections are often what determine the final champion. This race design logic—“first exhaust the riders with distance, then create variables with late-race terrain”—makes Milan-Sanremo frequently deliver breathtaking tactical duels and sprint battles in the final phase, earning the race descriptions such as “a sprinter’s endurance test, an endurance rider’s sprint test”—meaning the race simultaneously tests riders’ long-distance endurance and final sprint explosiveness, and neither can be lacking.

Tour of Flanders: Belgium’s Cobbles and Steep Climb Hell

Race Characteristics: The Ultimate Test of Steep Cobbled Climbs

The Tour of Flanders takes place in the Flemish region of Belgium. Most sources indicate that this race was also founded in the early 20th century and is one of the most prestigious annual events in Belgian cycling culture. In stark contrast to Milan-Sanremo’s long, flat characteristics, the Tour of Flanders’ defining feature is the large number of narrow, steep, short climbs paved with traditional cobblestones woven throughout the route. These sections have their own local names and are the race’s most recognizable core selling point.

These cobbled climb sections often feature remarkably steep gradients, and combined with the unique friction and grip characteristics of cobblestone surfaces, riders frequently need to fight for favorable positions on crowded, narrow sections during climbs. One small mistake—a slip, a crash, or getting boxed in—can cost them any chance of victory. This race characteristic of “terrain itself being the tactical core” means that the viewing focus of the Tour of Flanders often centers on how riders position themselves and manage their energy before and during these critical steep sections, rather than simply competing on who has the strongest overall fitness.

An Important Symbol of Belgian Cycling Culture

The Tour of Flanders holds an extremely high cultural status in Belgium. Most sources indicate that the race is regarded as an important symbol of local identity and cultural pride in the Flemish region. The race day draws enormous crowds along the route, and the strong festive atmosphere and connection to local culture make the Tour of Flanders more than just a bike race—it is an annual celebration belonging to the local community.

Paris-Roubaix: The Cobbled Trial of the Hell of the North

Race Characteristics: The Most Notorious Cobbled Sections of the Year

The Paris-Roubaix race is nicknamed by fans as the “Hell of the North” (L’Enfer du Nord). Most sources indicate that this race was also founded in a very early era and is the most extreme of the five Monuments in terms of the density and severity of its cobbled sections. The route passes through the industrial region of northern France, featuring numerous cobbled sectors of extremely primitive and rough road conditions. These sections have long lacked modern road surfacing maintenance, with uneven surfaces and violent vibrations that push riders’ bike-handling skills, equipment durability, and ability to withstand prolonged, intense vibration to the absolute limit.

Paris-Roubaix’s cobbled sections differ fundamentally from the Tour of Flanders’ cobbled climbs—the Tour of Flanders’ cobbles are mostly concentrated on short, steep climbs, while Paris-Roubaix’s cobbles are mostly long, rough sections on flat or gently rolling roads, testing riders’ ability to maintain control and power output under prolonged, severe vibration. Due to the unique nature of the course, riders often need to make special equipment adjustments before the race, such as increasing tire volume, adjusting tire pressure, and reinforcing frame vibration damping. This also makes Paris-Roubaix an important stage for equipment manufacturers to test and showcase product durability.

The Star-Rating System for Cobbled Sectors

One distinctive feature of Paris-Roubaix is that the organizers assign each cobbled sector a difficulty star rating based on its length and road severity, allowing fans and media to more intuitively understand what level of challenge lies ahead at any given point in the race. This rating system also reinforces the race’s narrative tension—when the broadcast mentions that riders are about to enter the highest-rated sectors, viewers naturally sharpen their focus, anticipating potential decisive race developments or unexpected crashes.

Liège-Bastogne-Liège: The Oldest Monument Race

Race Characteristics: Relentless Rolling Hills and Unpredictable Late-Spring Weather

Among the five Monument races, Liège-Bastogne-Liège is, according to most sources, the earliest founded and the longest in history, which is why it is often called “La Doyenne” (The Old Lady), signifying that the race is revered like a senior elder within the system of classic cycling races. The route passes through Belgium’s Ardennes region, characterized by endless rolling hills. While it lacks the notorious cobbled sections of the Tour of Flanders or Paris-Roubaix, the race demands constant handling of continuous climbs and descents throughout, placing quite severe demands on riders’ energy distribution and endurance management.

Additionally, Liège-Bastogne-Liège typically takes place in late spring, when the local weather is often changeable or even harsh. Low temperatures, strong winds, and rain can all add extra uncertainty and difficulty to the race, meaning that beyond the terrain challenge, riders frequently must cope with the additional physical and mental burden imposed by the weather.

Il Lombardia: The Season’s Grand Finale

Race Characteristics: An Autumn Foliage Climbing Feast in the Italian Lake District

Il Lombardia is the last Monument race of the season and is generally regarded as the benchmark event marking the official conclusion of the cycling season. It is therefore often called the “Race of the Falling Leaves,” echoing the fact that the race takes place during the European autumn, when the mountain scenery along the route transforms into autumn foliage. Most sources indicate that the route passes through the hills and mountainous terrain around the lake district of northern Italy, featuring multiple climbs of considerable difficulty that demand both climbing strength and late-race sprinting ability from riders.

As the season-closing Monument, Il Lombardia frequently attracts top riders who have peaked their form for the year or who wish to leave a defining performance at the end of the season. Because the course combines climbing with technical descents, the race often produces intense tactical battles in the final phase, drawing the season to a spectacular close.

The Tactical Logic Difference Between One-Day Races and Stage Races

No Tomorrow: One Mistake Can Cost Everything

To truly understand the unique appeal of Monument races, one must first understand the fundamental tactical difference between “one-day races” and “stage races” like the Tour de France. In a three-week stage race such as the Tour de France, even if a rider has a bad day or loses time in a crash, they theoretically still have opportunities in subsequent stages to gradually recover lost time through steady performances. The overall classification battle is a multi-week war of attrition and energy management. But Monument races are completely different—the race lasts only one day. Once you misposition yourself on a critical section, mismanage your energy, or unfortunately crash, you have effectively lost your chance at victory for that year. There is no next day to make up for it.

This high-risk “winner-takes-all” nature makes tactical decision-making in Monument races exceptionally intense and tense. Teams must devise precise positioning strategies before the race for specific sections (such as the critical cobbled sectors of the Tour of Flanders and Paris-Roubaix, or the decisive climbs at the end of Liège-Bastogne-Liège), and real-time communication and on-the-spot judgment between riders during the race can matter even more than raw physical numbers. For this reason, Monument races are often regarded as the ultimate test of a rider’s “race IQ” and ability to perform under pressure. Riders who rely purely on physical talent but lack tactical experience often struggle to consistently win these events.

Team Role Division: The Sacrifice of Domestiques and Team Leaders

Monument races are also contested by teams, with one designated team leader carrying the expectation of victory while the remaining teammates serve as domestiques, blockers, and supply carriers, securing favorable positions or saving energy for the leader at critical moments. Especially in cobble-heavy races like the Tour of Flanders and Paris-Roubaix, teammates positioning the leader favorably before entering cobbled sectors is often the key to preventing the leader from being caught in chaotic traffic, crashing due to poor position, or losing tactical initiative. This spirit of team sacrifice is an important detail worth watching in Monument races—although the camera focus is mostly on the eventual winner, several teammates are often quietly executing decisive tasks behind the scenes throughout the race.

Riders Who Can Dominate Multiple Monuments Are Extremely Rare

Because the terrain characteristics of the five Monument races differ enormously—Milan-Sanremo emphasizes long-distance endurance and a late sprint, the Tour of Flanders and Paris-Roubaix test cobbled handling and raw power, while Liège-Bastogne-Liège and Il Lombardia emphasize sustained climbing and rolling endurance—riders capable of excelling across multiple terrain types and contending for victory in different Monuments are extremely rare. Most top riders will, based on their physical attributes, selectively focus their training and season goals on one or two Monuments that best suit their characteristics, rather than hoping to dominate both cobbled races and climbing races simultaneously—these two categories impose quite distinct trade-offs in terms of body type, power, and endurance. Riders who are bulky and excel at maintaining high output on cobblestones typically struggle in the lightweight climbing demands of Liège-Bastogne-Liège or Il Lombardia; and vice versa.

Precisely because of this high degree of specialization created by terrain differences, any rider who can win multiple Monuments in their career—especially across both cobbled and climbing terrain types—is often regarded as one of the most complete and greatest riders in cycling history. This is also a key reason why Monument races hold such a lofty place in fans’ hearts and are difficult to replace with newer events.

Overview Comparison of the Five Monument Races

For readers to grasp the core differences among the five Monuments at a glance, the following table summarizes each race’s terrain characteristics, host region, and historical titles:

Why the “Monuments” Hold Such Lofty Status

The Cultural Depth Brought by Long History

The five Monument races were mostly founded over a century ago. This accumulation of history means each race carries a wealth of legendary stories, classic battles, and local cultural sentiment—a cultural depth that new events cannot replicate in a short time. For riders, being able to leave their mark on these historic courses is, in a sense, standing on the same stage as countless legendary riders from the past century. This cross-generational sense of historical connection is one of the key reasons Monument races hold such high status and cannot be easily replaced, and it is also the core appeal that continues to move cycling fans around the world.

The Terrain Itself Is the Strongest Fair Selection Mechanism

The terrain design of the five Monuments—whether Milan-Sanremo’s long-distance attrition, the cobbled trials of the Tour of Flanders and Paris-Roubaix, the rolling hills of Liège-Bastogne-Liège, or the climbs and technical descents of Il Lombardia—all feature a high degree of terrain uniqueness and difficulty thresholds. This harsh terrain testing functions, to some extent, as a natural selection mechanism—only riders with truly well-rounded abilities who can handle special terrain challenges have the chance to emerge victorious. This is why a Monument title is widely regarded within the professional peloton as being equal to—or even harder to achieve than—a Tour de France stage win.

Insights for Taiwanese Cyclists in Watching and Training

For Taiwanese cyclists, although it is difficult to personally experience these European courses, observing through broadcasts how riders handle cobbled sections’ bike-handling techniques and how they distribute energy across rolling terrain can offer plenty of practical riding inspiration. For example, when facing the occasional potholes, construction zones, or gravel surfaces on Taiwan’s riverside bike paths, observing how professional riders control their center of gravity over uneven surfaces has reference value. The energy distribution logic of Liège-Bastogne-Liège’s continuous rolling hills is also well suited for comparison with Taiwan’s routes like the Beiyi Highway or Fengguizui, which feature dense elevation changes—prompting reflection on whether you are overexerting yourself in the early stages, leaving you struggling on later climbs.

Furthermore, Milan-Sanremo’s “long-distance attrition first, decisive finale later” race structure serves as an excellent reference model for pacing strategies in long-distance challenge events. Rather than rushing to attack in the early stages and burning through glycogen and muscular reserves, learning from professional riders’ pacing philosophy of maintaining a steady rhythm early and conserving energy for critical late-race terrain is especially practical for cyclists preparing for long-distance endurance events such as the Wuling Challenge or round-island rides.

Extended Thinking Points for Taiwanese Cyclists

• Understanding the terrain characteristics of each of the five Monuments helps fans more accurately anticipate where decisive battles may occur during a race, greatly enhancing the overall viewing experience and on-edge excitement.
• The equipment adjustment logic for cobbled sections (such as wider tires and adjusted tire pressure) can also be applied analogously to Taiwan’s rougher challenge routes, industrial roads, or forest trails—considering whether your tire pressure and width settings suit the road conditions you plan to ride, avoiding instability or increased puncture risk from overly high pressure.
• The long history of Monument races reminds us that race culture takes years to build, which holds reference value for the long-term development of local Taiwanese cycling events and challenges—brand stories and local connections often retain long-term participants better than the scale of any single year’s event.
• Training insights from Liège-Bastogne-Liège’s continuous rolling terrain: when riding routes with constant elevation changes, practicing balanced energy distribution and avoiding excessive early expenditure is the key skill for handling such terrain. It is worth deliberately practicing repeatedly on similar routes in Taiwan to gradually build your own rhythm.

The five Monument races are among the most precious assets in the history and culture of cycling. Each, through its unique terrain challenges and long historical legacy, constructs the most prestigious one-day race honor system recognized by the professional peloton. When the next season arrives and these classic races take the stage one by one, use the terrain characteristics and historical context introduced in this article to rediscover these five cycling legends spanning over a century. Also try observing from a tactical perspective how each team positions and protects its leader—you will find that these “winner-takes-all” races are actually far more gripping and demanding of a team’s collective on-the-spot intelligence and cohesion than any single stage of a stage race.
