the 4K's

As if those amazingly steep and nasty hills aren't tough enough, in Flanders they're filled with cobbles. It just doesn't make sense for non-Flandriens. To many, cycling on this terrain would be considered inhumane. Yet these are fundamental to the Flemish interpretation of the sport. Don't go home without experiencing the four K's of Flandrien heritage: the fabled Koppenberg, the everlasting Kwaremont, mythical Kapelmuur and ferocious Kemmelberg. After that you'll be KO'd, consider that the fifth 'K'.
