What a day for a ride!
For anyone interested I ended up leaving the Burke VRE around 7ish and took roughly this route: http://www.gmap-pedometer.com/?r=6866270
Next time I’ll definitely cut straight up to Wakefield instead of what I did this time basically riding completely around Lake Accotink. Otherwise for anyone comfortable with the mileage and not interested in riding too many roads this was a really nice route. Some gravel and dirt but pretty flat for the most part and perfectly rideable with cross tires or your typical hybrid tires.
Hope everyone enjoyed the morning and thanks for the responses from everyone.
