I will say that any of the four loops up top are great for riding to the trails. There's a trailhead on both sides of the road just past the guard shack that allows you to access both sides of the park. Coming from camp, you'll make a left just past the guard shack into the woods to cross over rte345 and access the shed road/turkey point trails which iirc is about a 7 mile loop - it's a challenging loop, usually done clockwise. There's a long, rocky descent and a long climb back out. The remainder/bulk of the trails, which includes the race course are to your right. If you've done the race, you might actually remember passing some camp sites - these sites are on the four upper camp loops - either A, B, C, or D - I cant remember which, but they're all close.
