Tour of Flanders TR meet-up

Anybody ever done the Tour of Flanders Summer Edition ?

I’ve booked a week off in Oudenaarde and it turns out the first weekend has this going on and it will likely impact what was supposed to be a week of easy rides across East/West Flanders and Northern France. But it seems rude not to do it.

Trouble is i’m generally put off by so many riders (i think this is 4000). Do you think the climbs will still be crowded with the smaller numbers than the main sportive ?
