In September I rode across the Katy as part of a cross-country trip. A couple notes I'd make: Re: water, there aren't nearly as many places to get water as you'd find on the road. Two water bottles should be fine - just never pass a chance to fill 'em up. Second note would be a response to the "tire question" above - someone mentioned wondering if narrower tires would be better. I made my trip on a road bike with 25cm tires - just slightly wider than the normal 23cm tires that most road bikes have. This sort of crushed rock surface would be much better on at least 28's. Wider tires are better on this surface. It was dry, so it was never a problem for me, but I could definitely feel the drag.
Overall, a beautiful trail and a wonderful ride. I did mostly 100+ mile days across the country, but shorted them up on the Katy, which I'm glad I did.
