A1. Rik Van Looy, “The Emperor of Herentals.” The Belgian champion’s versatility was unmatched—he could sprint with the fastest, survive the cobbles with the hardest men, and conquer the Ardennes hills with the climbers. Van Looy won Milano-Sanremo (1958), Ronde van Vlaanderen (1959, 1962), Paris-Roubaix (1961, 1962, 1965), Liège-Bastogne-Liège (1961), Il Lombardia (1959), Gent-Wevelgem (1956, 1957, 1962), La Flèche Wallonne (1968), and Paris-Tours (1959, 1967). In completing the set of all five Monuments in 1961 with his victories in Paris-Roubaix and Liège-Bastogne-Liège, Van Looy became the first rider to achieve this feat. Only two others have since joined him: Eddy Merckx (who completed his set in 1971) and Roger De Vlaeminck (who completed his in 1977). But neither Merckx nor De Vlaeminck won all eight original classics—Merckx won seven (never Paris-Tours), and De Vlaeminck won six (never Gent-Wevelgem or Paris-Tours). Van Looy’s eight-classic sweep, combined with his two World Championship road titles (1960, 1961), cements his status as the most complete classics rider in history.
A2. Eight riders have achieved the Ardennes Double across eleven total instances, but no rider has accomplished it both before and after the 1985 calendar change. Before 1985, when both races were held on the weekend: Ferdi Kübler (1951, 1952), Stan Ockers (1955), and Eddy Merckx (1972). After 1985, with La Flèche on Wednesday: Moreno Argentin (1991), Davide Rebellin (2004), Alejandro Valverde (2006, 2015, 2017), Philippe Gilbert (2011), and Tadej Pogačar (2025). The Wednesday-Sunday format demands that riders peak twice within five days—a fundamentally different physiological challenge than the pre-1985 weekend double.
A3. Rik Van Looy, in 1962. The Emperor won the Ronde van Vlaanderen on April 1, Gent-Wevelgem on April 4, and Paris-Roubaix on April 8—three major cobbled classics in eight days. When Gent-Wevelgem moved to the Sunday before the Ronde in 2010, this triple became permanently impossible, as the race now precedes rather than follows Flanders. In 2012, Tom Boonen did actually win all three races on 3 consecutive Sundays (fifteen days). While this required him to maintain his form over a longer period of time, it also allowed him more rest between races. How this compares to the true Holy Week Triple is a matter for debate.
A4. Eddy Merckx accomplished this feat four times (1969, 1971, 1972, 1975), while Tadej Pogačar matched the achievement once in 2025 with victories in the Ronde van Vlaanderen, Liège-Bastogne-Liège, and Il Lombardia. Fifty years separated Merckx’s final three-Monument season from Pogačar’s.
A5. Eleven riders have achieved the Flanders-Roubaix double across thirteen instances. Tom Boonen (2005, 2012) and Fabian Cancellara (2010, 2013) are the only riders to have done it twice. The others: Heiri Suter (1923), Romain Gijssels (1932), Gaston Rebry (1934), Raymond Impanis (1954), Fred De Bruyne (1957), Rik Van Looy (1962), Roger De Vlaeminck (1977), Peter Van Petegem (2003), and Mathieu van der Poel (2024).
A6. Zero and one. In fourteen starts at Paris-Roubaix, De Vlaeminck abandoned only once (1980). In the thirteen editions he completed, he finished: first four times (1972, 1974, 1975, 1977), second four times, third once, fifth once, sixth once, and seventh twice. He never finished outside the top seven when he reached the vélodrome—an average finish of 3.1 across his completed races.
A7. The Ronde van Vlaanderen. Kelly finished second in 1984, 1986, and 1987 but never stood atop the podium in Oudenaarde. His nine Monument victories came from four races: Milano-Sanremo (1986, 1992), Paris-Roubaix (1984, 1986), Liège-Bastogne-Liège (1984, 1989), and Il Lombardia (1983, 1985, 1991).
A8. Octave Lapize (1909–1911), Francesco Moser (1978–1980), and Mathieu van der Poel (2023–2025). Van der Poel’s 2024 edition set the record for fastest average speed at 47.85 km/h.
A9. Pogačar became the first rider ever to finish on the podium in all five Monuments in the same season. He won three (Ronde van Vlaanderen, Liège-Bastogne-Liège, and Il Lombardia—his fifth consecutive Lombardia victory, finished second in Paris-Roubaix after crashing with approximately 38 kilometers remaining, and placed third in Milano-Sanremo. Bonus: While Fausto Coppi also won 5 Giri di Lombardia (4 consecutively from 1946-1949, 1954), Pogačar was the first to do so consecutively.
