E3 may have started out as a tribute to a motorway, but nowadays it is an explicit dress rehearsal for de Ronde.The way the race circles around the Flemish Ardennes to catch the middle set of Ronde climbs is straight out of some Flemish coach's training guide.G-W,on the other hand, circles out to the west, occasionally overlapping with the Ronde route but not taking in any of the climbs.E3 gets the upper hand if you're talking about rehearsing specific moments of de Ronde,but otherwise the advantage is not that great.First,the Tour of Flanders tests your ability to withstand more than just the Koppenberg.
