I am a former Dalton Guy who has also done Natchez Trace,
I always say that 85 miles on the Katy is like a century on the road. The great thing about the Katy is that it is flat and tree lined so there are not really hills, and there is much less trouble with wind as compared to riding on the road. The surface is hard with a loose top, so there is a little more rolling resistance. The down side, for me anyway, is that just like there are no hills to climb, there are no hills to coast down. Said another way, the rolling resistance is more or less constant, and that means that it requires a different type of "Being in shape". Not bad, just a little different. I find that surface will cost me about 2-3 mph as compared to pavement, so that is something to consider too. (although if you've ever ridden a newly chip and sealed road, I'd say Katy is faster than that with less rolling resistance).
If you think that 75 on Natchez is a good ride, then 60-70 on the Katy would be a good amount.
