Cathy,
The Katy is not paved. It's crushed limestone all the way except a few miles on street in Sedalia. Your other alternative is the Creve Coeur Park connector/extension which is paved but no shade. The link to it is on this website here (top page) http://www.bikekatytrail.com/SideTrails.asp
You can park at the public parking at page extension here

The trail is at the end of the parking lot. Left turn will take you down to the Katy, but right turn will take you to the CC PAVED trail. Crossing the MO rive is pleasant and safe. The trail is less than 4 miles long and will take you to CC lake which is very nice. There is a Round About at the end of the trail. Either left or right will take you to the lake (I would go left then right to cross over a rusted bridge). Follow the path around the lake (3.2 miles) and you will end up at the Round About (passing the rusted bridge on your left). If you get lost in the park, ask a biker. Many joggers do not know of the CC connector existence
