Nice OP there.
So does the World Championships, FW and so will RVV
I would agree that circuits can be boring and dont neccesarily do the best job of making the race a "Tour" of Poland, but on the other hand, its good for the fans, offers something different, can make a stage very hard if 1 very hard climb is repeated many times.
Also it does bring the race around the country unlike the Tour de Melbourne Suburbs.
But none of these things neccearily make it boring.
While it has arguably had the worst field of all WT races in the last 2 years, I think most would agree that it has been a pretty exciting race.
TDU for me, followed closely by Beijing and Eneco.
