From the Organizer
Two emails have gone out. One to the 2025 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 email has gone out to our 2024 4.4 Mile Swimmers who were unable to join us in 2025.
If you fall in to either of these categories and didn't receive an email from us on Sept 30th, 2025, please reach out ASAP at info@bayswim.com

About This Sport
Endurance Grid is here to help you understand the sport, decide if it's the right fit, and learn how to prepare. For course distances, logistics, and race-day specifics, always defer to the race organizer's event page.
Swimming events drop you into something that demands navigation, feel, and focus all at once. It's a sport that rewards the quietly competitive — the ones who do the work in the water before anyone's watching.
Open water races from 1 mile to marathon distance. Just you, the water, and whatever you've got left.
