Paved bike trails and roads that are currently closed to motorized traffic.
Easy riding, beautiful scenery, and fresh air in the middle of the city.
There are multiple points of entry to the park. At the southern end there is the National Mall. The northern end of the trail goes to Lake Needwood.
I do an out an back from Broadbranch road to Randolph Road, and a couple of extra hills, but it can be an almost flat ride if you want it to be.
