I considered Campenaerts to be a one-thrick-pony for some years. When he was out of contract and didn't immediately get to sign a new one, I even feared for his career.
I reckon he realized at that moment that he had to divert some of his attention at the road (and not only trying to prepare for TT), as he clearly wasn't dominant in TT.
Today, I am very happy he won. He showed he can finish off a road race and it was very well deserved. He raced with grinta, panache, agression,...and even some tactical nous. Everyhing needed to win a race!
