Parking Map





Is the course hilly?

YES! There are some big hills, but without the hills you wouldn't get the fabulous downhill finish.... Enjoy them, embrace them, curse them, but rest assured they'll be on the course. There are some steep hills so plan on hiking or walking the big ones and then you enjoy the wind in your hair as you blaze downhill for your epic finish. 

Is there is a time limit?

There is no cut-off for the 3 mile and 6 mile run. For the Sirena 13.1 mile and the 9 mile run, you will need to keep a 25 min/mile pace.

We will need you to hit the third aid station (Summit and Skyline Trails) by 11:30 am in order to continue.


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.  We strongly suggest that you carry at least 20 OZs of water at all times.


Can I run with a baby stroller?

Unfortunately, the trails are NOT suitable for baby strollers. 


Do you have prizes for winners?
Yes! We will have an awards ceremony at the expo. Awards are given to the 1st, 2nd, and 3rd place overall winners for each distance and 1st, 2nd, and 3rd place winners of each age group. Age groups are based in 10 year increments. You must be present at the awards ceremony to pick up your award.  Awards will not be mailed out.

Bring your PHOTO IDENTIFICATION (ID) or a copy of your ID in order to receive your packet. A valid driver’s license or a valid passport is best. Minors are not required to show a photo ID. 


What time should we be there on race day?
Packet pick up opens at 8:00 a.m. We recommend you get there at that time to get your packet and get ready for the race.

How soon does one need to register for the event?
The earlier, the better. Registration prices increase as the event date gets closer.

How many do I need in my group to be eligible for a group discount code?
6 or more.



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.

Do I have to wear my paper, race number?

Yes, you are required to run with your bib number. This is used for timing, identification, and race photos. 

I heard this event uses Chip Timing. What is Chip Timing?
Chip timing allows us to record your time using a computer and gives the most accurate results. Your timing chip is attached to your bib.
