Just wanted to pass on a cycling route I recently discovered and really like for the Saturday long ride.
Prince William Forest Park in Dumfries, VA, has a great 7-mile loop, as part of an 11-mile paved road called Scenic Drive: https://www.nps.gov/prwi/planyourvisit/bicycling.htm https://rootsrated.com/washington-dc/cycling/prince-william-forest-park-cycling
It’s light traffic, and the cars that are on the road are limited to 25mph and used to seeing cyclists, plus there’s a dedicated bike lane around about a third of it. It’s a great surface, and lovely place to ride in the forest – some hills (check out Hyperventilation Hill on Strava!), but mostly rolling/flat. Only downside is you have to not mind doing loops, and the I-95 south to get there gets a lot of traffic on Saturdays, so the earlier you can go, the better.
Happy cycling (and watch out for deer crossing)!
