I'm doing the New York City Triathlon on Sunday morning and want to know if I'm swimming with, or against the current. Here's a link to the tide chart I referenced: http://www.columbia.edu/~tedb/tri/tideChart.html and the tool used to construct it: http://tbone.biol.sc.edu/tide/tideshow.cgi My guess is that folks starting earlier in the day will have the current against them, but that it will weaken as the tide changes. The swim starts at 99th street and goes to 79th Street. More on the event itself: http://www.nyctri.com/. Thanks for taking a look!
