I've ridden the entire Katy Trail 7 times, and will probably ride the entire trail again this June. If you're seriously condsidering a great organized ride, consider the Missouri Dept of Natural Resources' Katy Trail Ride. It's a week long ride, camping, breakfast, dinner and SAG support provided. Go to www.katytrailstatepark.com for details.
The trail is made from pug, a loose gravel material. I would recommend a cycle-cross or hybrid for the ride. I ride my road bike that has 27mm tires and have only had two flats in those seven rides. Not bad odds.
The towns are about 10 miles apart, but are very small towns, some are only a few hundred people. There are very few bike shops along the way. Make sure to carry a flat kit, tube, pump, etc. You might also consider taking granola bars, fruit and plenty of water. I always take my Camel Bak with me. Some of the towns have well water and it's rather rusty.
You might also check out "The Katy Trail Guide Book." It's a great reference if you've never been on the trail. The Rocheport area is my favorite portion of the entire 225 mile trail.
Have fun!
