We have ridden West to East several times. Going this direction, there are some definite inclines before Sedalia, a few miles before Cliffton City (i think this one is the longest/steepest) and then pretty much uphill/downhill grades all the way from Cliffton City until about 3 miles before Boonville, at which time you get a nice steady downhill into Boonville. After that, it's pretty much flat.
It does however, make a huge difference if you are riding these during the heat of the day or not. I find them to be pretty easy unless it's 1 - 4 pm on a hot day. Regardless, I have had heat problems before, however on our last trip in June 09 I made a concentrated effort to hydrate and had no problems at all. Hydration makes all the difference!
