This trail system is all singletrack. There is nothing technical other than switchbacks, and it has some short but steep climbs. Access it from any trailhead, pick a loop and do several laps.
The climbs are good exercise, the switchbacks keep you on your toes and the view of the front range is amazing.
If you live in the area, this is a great after work ride, or for getting in shape after a long winter.
