About
The Potomac River Run Half Marathon is a 21.1km (13.1‑mile) half‑marathon held along the scenic Chesapeake & Ohio Canal Towpath in Washington, D.C. The course is praised for being nearly flat, shaded, and almost entirely unpaved gravel, offering a peaceful and fast route rated as “the easiest trail marathon & half in America”.
