One day membership - the 1-day membership allows you to become a member of the club and participate in a single day club sponsored training event. Before you register for the event, you must first become a daily member or annual member.. If you plan to participate in more than one event this season, you may want to consider joining the club for the entire year. If you are joining for a single day event, please be ready to show your 1-day membership on your phone at registration on the day of the event. Our open water swims are a popular use of this membership level.
