Ran the Mills Creek - Turkey Pen loop in the same direction as described. Ran alone carrying two water bottles, which was plenty on a cool morning (low 40s, starting at 7 AM in September). Really nice route --only saw a couple of mountain bikers on the trail. Surface of the trail is runnable throughout but sometimes a bit too steep to give running an advantage over walking. Trail mainly free of vegetation but some stinging nettles slapping the shins near the end.
