Anyone have a link showing the profile of this stage (preferably with grade %). The reason I ask is that the winning ride was about 28.5 mph. While it's way faster than I could ever hope to go, it doesn't seem especially fast for these riders for this distance. In fact, given the threads we see here about average speed, it seems downright slow. The commentary mentioned some hills, but it didn't seem like anything too much.

Was the speed due to no drafting, accumulated fatigue or was it simply much hillier than the coverage made it seem? Or was there some other factor I'm not considering?
