Good race. QSF ripped the race apart early and made life tough for everyone. Guess no one had Lampaert as their pick. Will be good to see if they can use their strength in numbers to the same effect in RVV.
As for Ghent, I was there for the Flanders sportive once in 2012. Awesome trip. Would love to go again.
Maybe you can still ride the sportive route. It is on open roads so technically you're not jumping in illegally on a closed route. You'll be just another cyclist out on a ride. Just follow the signposted directions. Or the thousands of other cyclists streaming by :-)
Oudenaarde is about 20 km away from Ghent on a bike path by the river. That is where the 141 km course starts and ends, and takes in plenty of the bergs and cobbles
http://www.sport.be/...rs/2017/en/parcours/ Plenty of options to watch the race around Oudenaarde on Sunday. Go early. It will be PACKED!
Walk around town. Drink beer.
If you're up for it, drive across to France and ride the Roubaix route as well.
