- Our Open Water Swims (OWS) are non-lifeguarded, swim-at-your-own-risk events. As such, it is imperative that you be certain of your comfort level and ability to OWS. These are not designed for, nor should they be used for learning how to swim, or for inexperienced open water swimmers. An inexperienced OWS is a danger to themselves, and those around them. If you are not certain about your OWS capabilities, we suggest practicing at a lifeguarded swim beach or at a event designated for beginning open water swimming.
- There is NO guarantee of access to changing rooms/lockers, or gear watch on the beach.
- A swim buoy with a dry pouch is useful to bring your phone and keys with you on the swim.
