it's an 8 mile loop, with 4 medium climbs (one of which is paved, others are fire road) and one very short, steep and loose climb (doable on the granny gear). you'll encounter 3 major flat areas where you can really crank it to get some high speeds (sandy in some parts), the rest is singletrack, a lot of up and down stuff, a little technical depending on your ability and speed. i highly recommend you ride it twice before you race on it (like on a saturday), and look out for opportunities to use the concrete drainage areas along the race track, that definitely helps in avoiding the sandy parts. you can pretty much do the climbs on the middle ring. i would consider this pretty much a fast course, so be ready all the climbs are short
