Hey,
Last year there were over 250 participants so there are probably a lot of people training right now. Team in Training is a great option if you are looking for help training. You get expert coaching from myself, and two other coaches, Sue and Tara. You get 8 training sessions, 3 in a pool, and 5 outdoors in the Hudson.
Training in the Hudson is a good place to train if you do it safely with others. You should not just go jump in the Hudson if you are not prepared and if you do not have proper safety precautions in place.
Rye Beach is also a great place to train, in some ways safer than the Hudson, but again make sure safety precautions have been taken care of. Rivers, Sounds, and Oceans are things to have a healthy respect for.
I would be happy to share training tips with you if you have specific questions. Or are looking for some guidance.
