Drop in at
BikeWorld (three locations) in San Antonio and chat with the employees, other customers and pick up the brochures. You'll have more trails and routes to ride than you know what to do with!
Quickies, without links because I'm in a hurry:
* Hill Country State Natural Area
* McAllister Park
* OP Schnabel
* Canyon Lake (Madrone Trail)
* Leon Creek Greenbelt
* Rocky Hill Ranch
* Guadalupe River State Park
Check out BikeMojo.com's forums for other places to ride:

We'll be expanding the bicycling and MTB coverage here on WildTexas.com soon. Hubby and I love mountain biking, but right now hubby's training to participate in the MS150 "Bike to the Beach" -- 150 mile ride over two days from San Antonio to Corpus Christi, Texas. His blog is
Bike Geek. Right now it's mostly road cycling but he has posted stuff from his various mountain biking rides as well (at least a couple).
