Historical water temperatures are mid-to-low 70s in mid-October, so the expected temperature is ~74-75F. USMS rules allow wetsuits if the water temperature is below 78.0F.
Awards will be presented to male and female Top-3 Overall, as well as Top 3 in each age group in 10-year increments (18-29, 30-39, 40-49...).
USMS sanction is pending. All swimmers MUST be members of USMS.

From Endurance Grid
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 take place in lakes, rivers, bays, and oceans. Distances can run anywhere from a short 500m swim to 10K marathon events. Just you and the water.
