20 Bridges is a 28.5-mile (48.5-kilometer) swim around Manhattan Island traditionally completed in a counter-clockwise direction. It’s a full loop, with an in-water start and finish. Regardless of which side you breath on, you’ll have interesting scenery the whole time! This includes many bridges, of course, which swimmers often choose to backstroke underneath so as to best enjoy the view (see list below). Other course highlights include famed skyscrapers such as the Empire State Building and the Freedom Tower, sites where world leaders come together such as the United Nations, natural areas like Randall’s Island and Inwood Hill Park, and the many piers, neighborhoods, and types of transportation that keep New York humming.

The swim travels through three “rivers” that are actually all tidal straits or estuaries; no freshwater here. The East River, connecting New York Harbor to Long Island Sound, has some ripping-fast tides that will have you shooting under the iconic Brooklyn Bridge and other spans as you pass the boroughs of Brooklyn and Queens. The Harlem River, connecting the East River to the Hudson, is quite mellow by comparison, with relatively calm waters and a slower current. Though it’s just 8 miles long, the Harlem River is crossed by 15 bridges, most of them between Manhattan and the Bronx! Then, of course, is the mighty Hudson, separating Manhattan from the state of New Jersey. The only bridge during this stretch is the magnificent George Washington Bridge, with the Little Red Lighthouse tucked at its base. The Hudson can get quite choppy in the afternoon due to all the boat action, especially if there is wind coming up from the Harbor.

NYOW runs the 20 Bridges swim from two different start locations, depending on tides and daylight hours. These locations are Pier A, Battery Park, in Lower Manhattan, and Mill Rock on the Upper East Side. Click on the relevant map for mile markers. Regardless of where the swim starts, boat loading for all participants takes place in Lower Manhattan on the West Side. Swimmers and volunteers may wish to keep this in mind if booking accommodations.

The swim around Manhattan is part of the famed Triple Crown of Open Water Swimming, together with the English Channel (between England and France) and Catalina Channel (in California). Though considerably longer in distance that those other two swims, 20 Bridges generally takes less time when scheduled with advantageous tidal currents, as is NYOW’s practice.

The cost for 20 Bridges 2022 is $4600 per solo; $3600 for 25 years-old and under; $2800 per swimmer (maximum 2 swimmers) tandem. For the 20 Bridges Reverse (i.e., clockwise), the price is higher due to the swim taking significantly longer: $5,200 per solo, $3,550 per swimmer (maximum 2 swimmers) tandem.

Entry fees include a designated support boat, kayak/kayaker, observer, and GPS tracking. Swimmers are requested to bring one or two (max.) crew persons older than 16 years to support them from their escort boat. Operation expenses have increased considerably this season. This is reflected by the higher entry fees.
