It's not just a race bike. I've had mine for a few years and ride it general XC for the most part. I've also ridden it out in Moab and wherever I ride. The brain is a great function and if you'll be doing mostly cross country and racing, it sounds like a great way to go.
If I was living in Moab, I'd get an Enduro or something along those lines. For now, I'm content with my Epic and can recommend it without hesitation.
