Columbia to Rocheport is fairly shaded. Rocheport to New Franklin is more exposed to the sun and with the farm fields all around, is quite hot and humid. Once you hit Boonville, you have hills to Pilot Grove, but it is covered by the canopy. Most of the rest of the way to Sedalia is covered. But you should always wear sunscreen and have lots of water. That's going to be a fairly long ride on a hot day. Hopefully you will get some cloud cover.
