A friend and I are getting ready for our 12th(?) Katy Trail trip, and love it! Pack VERY light, just something to wear in the evening and your toothbrush. Nearly every B&B and small hotel allows you to do laundry, or you can wash your bike shorts and shirt and socks out in the sink. I prefer a small square bag on a rack to panniers (saddle bags) because it doesn't weigh you down as much and forces you to pack only the necessities. Do take a light rain jacket, because MO weather is unpredictable.
Just DO IT, and enjoy!!! We are in our late 50's, and typically don't bike at all between our annual trips on the Katy Trail. And we do just fine. Oh, ride west to east (toward St Charles) for more downhill ease.
We love doing around 40-45 miles per day. It doesn't kill you, and allows time in the evening to enjoy a good meal, wine (you're biking thru MO's wine region, after all), and conversation. I've (fingers crossed, knocking on wood) never had a flat on the Katy Trail, but it's happened often to people I ride with. The thorns are terrible!
