Beautiful fun town with nice places to stop and eat. A couple of gas stations with easy Gatorade if you need to top off, or places to stop and grab lunch if you have more time

Along this scenic, generally well-maintained gravel road is a large horse farm. Be on the lookout for the horses grazing as you ride past.

This section of Hopewell Road, a forested, scenic road in Ashburn is quite steep. Be ready for some hard work if cycling up, or some fast riding if coming down! While the road is fairly quiet, its a bit narrow, so just be aware as you ride.

Beautiful stretch of smooth gravel. The road is lined with trees, so there is a lot of shade as you are riding, so this is a great option for a hot, sunny day.
