You're in luck - - WV has a thriving organization for MTB racing and they put on quite a few:

There is almost always a first-timer's class in every age category; and 30-39 is often one of the largest groups, so there stands a good chance of being enough to make a class.

Also check the I Play Outside web site (http://www.iplayoutside.com/Search/index.php) and filter the event schedule by XC MTB races - - some are the WVMBA series events but there are others too in your neck of the woods. IIRC, one of the once-regular posters on the site ("soccer mom" apclassic) runs or had something to do with the iplayoutside site. She was also an organizer of the Appalachian Classic MTB race, but that one may not be going on any more.

If you need more info, let me know and I can hook you up with another WVian who is still on BF occasionally who was a real avid MTB racer but now does mostly road. But I'm sure he's still plugged in to what's available out there and could give you some pointers.

Have fun . . . racing is a blast!
