In the 1920s Flemish track specialists dominated the race. Gérard Debaets, a specialist of six-day racing in the American circuit, won the race twice; in 1924 as one of only 17 finishers in dreadful weather conditions. Swiss Heiri Suter became the first foreign winner in 1923 and achieved the first ever cobbled races "double" win with Paris–Roubaix one week later.[23] In 1926, a group of ten sprinted to the finish.
