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.
