I should have picked this up by now, but clearly I haven't. How do all the Tours, Spring Classics, World Championships, the Pro Tour etc relate to each other, if at all? Does the Tour of CA count for anything beyond the joy & $$ of winning it? Are the World Championships that Boonen won simply a stand alone series of races, or do they reflect prior season wins? Does the Pro Tour matter for anything?
And is the World Cup the same as the World Championship?
