The swim involves a full counter-clockwise circumnavigation around Manhattan Island. There are three stages of the swim:

  • The First Leg is around Battery Park then north up the East River towards Hell’s Gate. The swimmers go under the Brooklyn Bridge, Manhattan Bridge and Williamsburg Bridge

  • The Second Leg is north into the Harlem River, through Spuyten Duyvil. This is a common route for boat traffic so it is important to keep left

  • The Third Leg is a straight swim south down the Hudson River to the starting point in Battery Park. The final leg takes swimmers under the George Washington Bridge. The challenge after the George Washington Bridge is to avoid being swept into the sewage treatment plant, between 145th to 135th Street. The second challenge is a number of boats coming out of the piers, especially between 50th and 23rd streets, which need to be avoided

As always – the key is to keep you head down and swim!
