I think running on trails is a pretty good workout, because every step is placed a little differently, and the variation in terrain, pace, and altitude make for an intense, varied, calorie burning workout. However, the pavement takes a different kind of toll on the knees, shins, and feet. You probably can not compare the one with the other, because it may tax the body in different ways. Go for it. Trail running is an awesome experience!
