It's easy to spot mountain bikers--they're the ones with scab-covered limbs talking animatedly about bonking while riding a wicked singletrack. Indeed, they are a peculiar lot, but only because of their passion for the sport. They don't seem to mind the murderous workouts--they actually celebrate sore muscles--as they attack intense rolling trails in pristine wilderness. The exhilaration of nailing a technical ride in the world's most stunning places is more than enough fuel for mountain bikers.
