Spectators are welcome!


Are men allowed to compete in a Mermaid event? - Yes! Men can register and participate. However, since Mermaid is primarily a women’s event (about 97-98% of participants are women), men are not eligible for awards.

Can I pick up my friend’s packet for them? - Yes! Bring a copy of their photo ID and we’ll give you their packet.

Do you have aid stations? What kind of liquid/food is on the race course? - Yes, we have plenty of aid stations. Water, Ultima Replenisher electrolyte drink, and Luna bars are available at aid stations along the course.

Should I register for an "Individual Age-Group" the "Family & Friends" or the "Athena?" - The Family & Friends Division was developed for athletes that want to start with friends or family. This category is also for anyone who wants to do the race without the pressure of "racing" in their age group. The "Family & Friends" division allows athletes of any age to start together and is often very popular with the first time and novice athletes. Please note: awards are NOT issued for 1st, 2nd or 3rd in the "Family & Friends" division. The "Individual Age-Group" division means that you are racing against the other athletes in your age-division and we award prizes for 1st, 2nd, and 3rd place. The "Athena" division is for athletes 165 lbs. and over who want to race against similar athletes for a 1st, 2nd and 3rd place prize. NOTE: There is no "Family and Friends" category for the Mighty Mermaid or the Duathlon.

What is the water temp? Do most participants wear a wetsuits? - The water temp for the Pacific Ocean is chilly and is typically in the low 60's degree range. Most all participants will wear a wetsuit.

Are we required to pick up race numbers the day before? - No, but we strongly recommend that you pick up your packet the before the race at a pre-race day packet pickup. This allows you to put your bike number, helmet number, and race number on prior to race morning.
