A classic Loudoun gravel loop I stole from Jim Strang, founder and co-owner of what was previously the region's largest bike shop chain (Spokes Etc.). Loads of gravel with the final several miles back to Philomont on the very pretty tarmac that is Snickersville Turnpike. We'll refuel at Greenheart Juice Shop in Aldie around Mile 40 so plan fueling and hydration accordingly...unfortunately, there aren't any great options earlier in the ride!
