I am new to trail running and ran in my first race Sat 24th. I am planning on running a 15k race in June and looking for a book or site on training, etc.
Welcome to trail running! It's probably one of my most favorite things to do. There's info on running training here, which is easily applicable to trail running too. Check out our running channel: http://www.active.com/running
Hard to tell you unless we know where you live.
Hi Rick, check out Born to Run by Chris McDougall for inspiration on train running and ultras.
