Starting Procedures | Location

Triathlon | Relay

For the swim, the beach will open at 5:45 am for open practice.  Please do not swim far out as all swimmers must be out of the water no later than 6:25 am.  Please adhere to this rule as failure to do so may impact the start of the event.  Race announcements and the national anthem will take place between 6:25 am and 6:40 am.

The Sprint distance will begin at 6:40 am.  It will be a rolling start sending off a few swimmers every few seconds.  You will self-seed yourself and is best to do by what you feel your estimated time will be.  Volunteers will be on the beach holding up signs with estimated swim times.  Begin to line up accordingly behind the proper time to self-seed.  The Sprint swim is a single counter clockwise loop that will follow the lime green buoys.  The Olympic distance will have similar rolling start and self-seeding that will begin by 6:55 am.  As with Sprint athletes, please look for volunteers holding up signs with estimated times and organize yourselves accordingly.  The Olympic swim is also a single counter clockwise loop which will have intermittent buoys and then large orange buoys signifying the two left turns.  Lifeguards in kayaks, as well as motor boats will line the outside of the course with the buoys on the inside. If you cannot complete the swim and are pulled from the water, you cannot continue the event per USAT rules. You must turn in your timing chip and leave the course.

Aid Stations

Race Management will have aid stations at every mile along the 5K Run Course complete with Water, Gatorade, Ice and portable restrooms.
