EDIT: Actually, looking closer, there are some kicks to that 10%+ range there on the switchbacks. If you turn on "Gradient" markers in that page, you can see them - they're all like 10-50 meters, but they are there.
At the hairpins the grades are steep on the actual ride. It just seemed too steep when I was on the bike and I couldn't turn the pedals anymore. RidewithGPS doesn't show it being that steep either.
It was only a short distance on Rouvy, but the simulation made it feel even harder that it is, plus I started in the middle of the uphill, not that there is any flat anywhere on the ride.
