Mermaid Dash

The Mermaid Dash is a great way to introduce girls to running and walking. The fun run/walk allows girls to participate and experience the joy of crossing the finish line in a safe and supportive environment. Mermaid Dashers receive a medal, finisher necklace and post race food. Parents are encouraged to let Mermaid Dashers run on their own, however a parent or guardian is welcome to run alongside young or shy Mermaid Dashers.

Directions and Accommodation

DIRECTIONS 

We suggest to arrive a minimum of 1 hour prior to your race. The Boulder Reservoir address is 5565 N. 51st Street. The crossroads are Reservoir Road and 51st Street. Directions are listed below or you can go to Google Maps.

You can enter onto 51st Street from the south or the north. We recommend you try entering from the North — directions below — instead of from Jay Road to avoid congestion and get parked more quickly.

From Diagonal Hwy (CO-119) going north, keep going to N. 63rd Street
Turn left (north) and drive up to Monarch Road.
Turn left (west) and take Monarch to 55th Street.
Turn left, and follow 55th (which turns into 51st) all the way down to parking at the Reservoir, on your left. 

If you're traveling south on Diagonal Hwy (CO 119)
Turn right (west) directly onto Monarch Road and follow directions above.

Note on Post-Race Parking Exit: The Boulder County Deputies on duty will direct you north out of the North parking lot as you exit, regardless of which way you came in. This is to avoid congestion on the Jay Road exit off of 51st Street.

The Boulder Reservoir has plenty of free parking. It's getting to a parking space that can be tricky. The single road that travels into the reservoir can make traffic a bit backed up. So, we strongly recommend that you arrive at least one hour before the start time and carpool if you can. Once you arrive, please follow the parking attendants' directions and hustle on in.
