The Potomac Heritage Trail is a 10-mile trail that runs parallel to the
                    George Washington Memorial Parkway between Theodore Roosevelt
                    Island and the American Legion Bridge along the Potomac River. This trail,
                    marked by blue blazes, is another little-known gem in urban D.C. It is hilly
                    and heavily forested with sycamore, oak, poplar and beech trees. At times
                    it can be steep and rocky and more suitable for hiking than running.

                    The trail intersects the Donaldson Run trail, which follows a rocky
                    streambed up to Potomac Overlook Regional Park. Potomac Overlook has
                    more than three miles of nature trails that are perfect for running. All are
                    extremely well maintained and many are covered with a soft bed of ground
                    mulch. Wildlife is everywhere and there are old homes, gardens and a
                    cemetery to view.  To get to Potomac Overlook, run north on the Heritage
                    Trail, which begins at the north end of the Roosevelt Island parking lot,
                    for about three miles (Fletcherâs Boat House will be across the river).
                    Shortly thereafter, the trail takes a sharp turn to the left along a stream.
                    Look for a steep trail that goes upstream. Follow it for a mile or so.
                    There are several stream crossings on rocks. Look for the brown-blazed
                    trail off to your left. This joins up with Potomac Overlook Parkâs trail system.
