Two emails will have gone out. One to the 2026 4.4 Mile Swimmers with information about the Early Bird program (complete the 4.4 mile swim with us and receive a special offer for the following year).
The other is a special invitation, to our 1 Mile Swimmers, who want to bypass the lottery for 2027 and guarantee their entry to 2027.
If you fall in to either of these categories and didn't receive an email from us by Sept 15th, please reach out ASAP at info@bayswim.com
