Last year's winner will not be at the start line and, therefore, will not be taking home either the larger cheque or another cobble-stone trophy. In this respect, the women's race is similar to the men's race that takes place on Sunday. However, there is a vast difference in the history of the events. The 2021 women's race was the first edition of a race. The men's race started in 1896. It is one of what are known as the five monuments. These are monumental one-day races in many ways. For example, the winner in each of the five men's races in 2021 took over six hours to complete the race. One race stretched to 6 hours and over 39 minutes.
The long history of the event allows us to look at the historical outcomes of the race. One such outcome of interest is the long-run distribution of winners. Below is the cumulative distribution of winners since 1946 for Paris-Roubaix. Another monument is included for comparison purposes, i.e. Tour of Flanders. Both have 76 winners but in the case of Paris-Roubaix it includes two winners after a controversy in 1949 and no winner in 2020 when the race was not run for pandemic related reasons. Of the 76 winners, Paris-Roubaix has 54 different individuals winning at least one race whereas the Tour of Flanders has 59.
