This is a low-key event, harkening back to the earlier days of open-water swimming, but there's nothing low-key about the challenges of following Gertrude Ederle's 17.5-Mile swim course from Battery Park to Sandy Hook, NJ. Recent swimmers have had to contend with severe chop, fog, and unseasonably warm temperatures as they made the crossing through New York Harbor, yet with today's knowledge of the tides, most participants cover the course faster Ederle's record, which lasted from 1925 until 2006. With especially fast tides in 2009, the record may drop again.
GPS maps showing the course routes for individual swimmers are now available. Please note that the red course line is only meant to provide some guidance to those who are viewing the map – it was not the official course.
