Potomac River Marathon and Half

The Potomac River Marathon and Half is an out and back marathon and half marathon held at Fletcher's Cove, 4940 Canal Road NW, Washington DC, on the C and O Canal Towpath. The course is USATF certified (DC21001RT) and runs on a narrow unpaved trail of crushed stone and packed dirt that is mostly flat and tree lined, with views of the Potomac River and historic canal locks and gatehouses.

Distances

  • Marathon 26.2 miles
  • Half marathon 13.1 miles

There are four aid stations placed roughly every two miles that provide water and Gatorade; portable toilets are available at each station and at the start and finish. First aid, course marshals, and bike support are present on the course. The marathon route passes aid stations approximately fifteen times; the half marathon passes them approximately eight times. Runners share the towpath with other users and bicyclists and are asked to keep to the right.

Entrants receive a technical shirt and finishers receive medals. Cash awards are offered for the top three overall men and women in each distance with specified prize amounts; to be eligible for cash awards runners must begin at the official race start. Parking and drop off are available near the start and finish at Fletcher's Cove, and additional parking or drop off may be available on Reservoir Road near The River School. Proceeds benefit affiliated charity partners and community foundations. Visit the organization's website for the most recent information.
