I believe it is just over 8 miles of one of the nicest parts of the trail, imo, to the Columbia spur. As for the spur, it depends where you start, from Flat Branch Park it's about the same distance, maybe a little farther, with more joggers, walkers, and cyclist. But, it is also a very nice ride with lots of shade for probably 3/4's of the way.
Sort of a toss up. You will have the shade of the bluffs in the morning coming from Rocheport but with fewer people. Having ridden the Katy Trail several times before, if it were me, I would check out the scenery of the MKT, it will probably be at a little slower pace though, but worth it, early is better. Enjoy your tour!
