I did the 2-mile last September and it was a fun race. There was one part of the course where the water was colder than the rest of it. The temperature was great and the tide was high This way, no issues with those rocks on the bay floor They can be treacherous.
There are alot of swims going on at the Jersey Shore. If you are really ambitious, there are some weekends where there is a Friday night OW swim and then a Saturday morning one. I did the AC one last weekend but there were several people there that did the Somers Point swim the night before.
