The loop begins at Monacan High School on Smoketree Dr. in Midlothian. Because it's a loop, however, you can pick it up anywhere along and always end up where you started. The entire loop is almost always rolling and under the cover of the road lining trees. There’s a pretty fast fast downhill stretch (speeds greater than 40 possible) along Old Bon Air Rd. followed by a steep graded climb back up to Forest Hill Ave. Once you reach Riverside Dr, be sure to take in the views along the river and let your legs to recover a bit for the climb up Old Gun Rd. This is a tough 2-mile climb; expect to be climbing anywhere from 10-20 minutes.
