The vast majority of the trail is flat as a pancake. The Osage Hills, located between Sedalia and Booneville, has some minor (but long) grades. It is nothing to worry about, and I think the Osage Hills may be the prettiest stretch of the trail. Any bike in good mechanical condition, including road bikes, will do just fine on the Katy.
