While I do not recommend using a road bike on the trail, it is possible. My recommendation would be to use the largest size tire that fits in the frame if you want to attempt it. This will make your bike a little more supple as there will be some soft/rough spots that may give you a hard time though. The nice thing about Cowboy Trail though is if the trail is not your cup of tea, HWY 275 is right there with a nice wide shoulder to ride on. Another option if you haven't checked out the Wabash Trace in Iowa, that might be another good spot to do this as that trail is pretty hard packed.
