Asphalt. Even in the Park.

Heres the rundown to the park

At the overpass, instead of turning right to stay on the BWI trail, go straight down Stoney Run Blvd. Go thru the light and turn left at the end to remain on Stoney Run. At the top of the hill turn right onto Ridge Rd. Follow Ridge Rd for a couple miles (mind the traffic circle). Ridge Rd ends at Furnace Rd at the bottom of a fun downhill. Turn left onto Furnace. Go past the Inn and keep on about 3/4 mile to a left onto Main Street in Elkridge. Go a couple hundred yards to a right on Levering Ave. Cross Rt-1 at the light and stay straight on Levering Ave. Levering turns into River Rd past the bottom of Lawyers Hill (a fun place for hill repeats). Stay straight and head right thru the barrier gate into the park. Theres a gap big enough for bikers and horses to get thru. Its still asphalt, but rough tar and chip and strewn with leaves and twigs. Be careful. Once thru you'll see a big parking lot straight ahead and an access road. Go to the right and cross over the river. Then bear left again onto the road just to the left of the barrier gate that goes across the the bottom of Gunn Rd. Follow this road into the woods onto the paved MUP at the end of the last parking lot. Follow this MUP along the river for about 1 1/2 miles to the steel foot bridge that spans the river. Cross the bridge to the access road on the other side. Theres a bathhouse on the other side if you need water or a natural break. Follow the access road back to where you came in and head out of the park the same way you came in. Once back on Furnace Rd, instead of heading back up Ridge, turn right on Race Rd. Follow Race Rd. for a couple miles to a left on Hanover Rd. Stay straight on Hanover to the end and turn right back onto Ridge. At the stop sight turn left on Stoney Run and head back to the overpass and get back on the BWI trail where you left off.

Addendum. If you fancy a hard climb, turn right onto Lawyers Hill Rd as you leave the park. Take Lawyers Hill all the way to its end on Montgomery Road. Turn left on Montgomery Road and cross Rt-1 at the light. Turn left on Main Street and follow to a right on Hanover Rd. Follow Hanover Road all the way back to Ridge Rd.

If you want, meet me at the Aircraft View Area parking lot 6pm on Friday and I'll personally show you the route. I'm doing an active reco ride and will be their anyway.
