What to expect on Piney Branch – Old Dominion Trail loop from Dunn Loring–Merrifield

The journey begins on the Washington & Old Dominion (W&OD) Trail, a former railroad bed offering a smooth, paved surface ideal for picking up speed.

This blend of surfaces and scenery makes it a great option for joggers who appreciate variety and don't mind a bit of a challenge after a smooth start.
