Luck and bike racing
So how lucky do you have to be to win Paris-Roubaix, or any bike race? Look at those cobbles, gasp at those crashes, and you could jump to the conclusion that you have to be pretty damn lucky, with the degree of good fortune depending on the degree of danger and the number of riders in the mix: more luck required for Paris-Roubaix or the Dengie Marshes, or any race ending with a bunch sprint; less luck for something hilly and decent surfaced where a strong rider will make a difference.
