Excellent moutain biking loop!
The trail on the map is The Cannonsburg State Game Area trail. Cannonsbug Ski Area has its own set of trails north of the trail mapped here. The two tracks are separate but there is a path linking them if you know where to look.
Awesome trail for mountain biking. The are a few gnarly hills to get your legs burning and some pretty technical areas. I would only recommend this trail to a somewhat experienced biker. This trail is the same as the Egypt Valley Trail.
Really a great place to bike or hike. The ski hill is quite a climb, but once you get to the top you are rewarded with a terrific view. If you're in the area, I'd recommend stopping by and seeing what you can find! There's also a nice stream before you reach the skill hill that is enjoyable.

Great MTN bike trail, not for a true beginner but I rode it with my 13yr old son. It has some good climbs and a few technical areas, not too rutted out but there is a fair amount of loose sand depending on weather. Its also 6 or 7 miles not 3 as in the description. Trail head is at the parking lot of the ski area and then head towards the hills and go left after you cross the creak.
