All single track with some nice s-turns through woods. A few good downhill and uphill sections going to and from a creekbed. On the far side of the main creekbed are some fun loops known as the "Blair Witch trails". Overall, it's not a bad place to ride considering the proximity to Richmond. You'll definitely get worked there.
Take the Ashland exit off of I-95 and follow Hwy 57 west for about 1.5 miles out of town. Turn left at Poor Farm Park (there is a middle school there + soccor fields). Park in the gravel lots. trails begin on either side of the woods.
