Yes, it's actually within a very short walking distance of the trail. The Katy actually goes along the Fairground property and you can see a good view of the other side of the race track (opposite the grandstand - I got a picture of it when I rode).
If you look at the Sedalia map as posted on this site, start by looking for Clarendon Road, and then follow the marked trail out to 65 highway. This section runs near the fairgrounds.
