The DC Marathon Swim
“When George Washington chose to build his Mount Vernon estate along the Potomac River, he declared the then-pristine body of water “the Nation’s river.” At the time, even dolphins were a common sight.” *

Georgetown to George Washington
The DC Marathon Swim is a 20.5 mile epic adventure from Chain Bridge to Mount Vernon approved by the Marathon Swimming Federation. Navigating your way through Washington DC in the Potomac River, tides, currents, changing winds will challenge your open water skills and endurance. Each mile takes you through history as you soak in the monuments and scenery unique to our Nation’s Capitol.
Ultra marathon swimmers, Denis Crean and Jim Loreto decided to be the first to swim through Washington DC and declare, one stroke at a time, that the Potomac is once again a swim-able river. This swim is conceived around the idea that the “Nation’s River” is accessible and flourishing with vibrant native life and worthy for all people to enjoy.
MISSION: We are dedicated to executing an annual challenging, international open water swimming event that unites all participants, spectators and citizens while promoting clean vibrant water in the Potomac River for all to enjoy.
DETAILS: Swim Open to 10-20 qualified swimmers and relays. All swimmers must be supported by crew, power boat (supplied), kayak/paddleboard (supplied if requested) and official observer (supplied). Cost is $3200 for solo swimmers. Relays are based on number of swimmers. Information will be firmed up as swim dates near. See FAQ for details.
Our objective is to provide every swimmer a safe opportunity to complete the entire swim. Unless constrained by safety concerns and/or permits, we will swim rain or shine, day and night. Potomac tides switch approximately every six hours, and with variable winds, that generate currents that assist and hinder your progress. Prepare yourself and your crew for difficult conditions, and immeasurable fun!
