Important Race Details

Light required: Headlamp or flashlight is required during this race

Race Field: Limited

Race Start: This will be a chip timed start, your time does not start until you cross the line.  In order to spread out runners and reduce the “hole-shot” backup, we will start racers in waves of approximately 30-40 racers at a time.  Full Marathon runners will be started first and given an approximate 5 minute head start. After that, please self seed according to the announcer’s instructions.

Chip Timing: All distances chip timed by MyLaps Bibtags system. The chips are attached to the back of your bib and are disposable so we do not need them back. Please wear your bibs on the front of your body and do not cover with heavy coats.

Parking: There is parking available in the park. Use the beach area lots first. Parking along the road is ok, but do not drive on the grass.

Facilities: Portables Only, at the start and each aid station
