Big Four (cycling)

The "Big Four" in cycling is a collective term, though its specific meaning can vary depending on the context and era being discussed. Generally, it refers to the four most prestigious and challenging one-day classic cycling races, revered for their historical significance, demanding courses, and ability to test a rider's skill, endurance, and tactical acumen across diverse terrains.

While there's no universally fixed list, the races most commonly associated with the "Big Four" designation are:

• Milan–San Remo: An Italian classic, typically held in March, known as "La Primavera" (the Spring Classic). Its long distance (around 300 km) and final climbs, particularly the Cipressa and Poggio, make it a test of endurance and explosive power.

• Tour of Flanders (Ronde van Vlaanderen): A Belgian classic, held in early April. It is characterized by its short, steep cobbled climbs known as "bergs" and treacherous narrow roads. It requires exceptional bike handling skills and strength.

• Paris–Roubaix: Another Belgian classic, held in mid-April, often called the "Hell of the North". It is famed for its long sections of cobblestone pavé, which create brutal riding conditions and a high rate of mechanical failures.

• Liège–Bastogne–Liège: A Belgian classic, held in late April, often nicknamed "La Doyenne" (the Old Lady) as it is the oldest of the five monuments. It is known for its long distance and numerous challenging climbs in the Ardennes region, making it a true test of climbing ability and endurance.

The term "Big Four" is sometimes used interchangeably with "Monuments of Cycling". However, the "Monuments" designation is the more widely accepted and standardized term, which also includes the aforementioned races. Using "Monuments" guarantees referencing Milan-San Remo, Tour of Flanders, Paris-Roubaix, Liège–Bastogne–Liège, and Il Lombardia. "Big Four" is a more informal and variable term.
