Registration includes a tech race shirt, a finisher medal, and a necklace. Participants may remove one or more swag items during registration to reduce the entry fee; listed savings are $8 for no shirt, $3 for no medal, and $3 for no necklace. Youth participants aged 19 and under receive a 20% discount automatically during registration.
Course maps are available for each distance. The virtual run requires registration by February 23 to help ensure packet delivery by race day. The Mermaid Dash encourages parents to allow children to run independently, though a parent or guardian may run alongside young or shy participants.
A credit policy is offered for those who cannot attend; credits require a request at least 10 days before the event, are valid through the following calendar year, and are nontransferable. Credit amounts for run events reflect the entry fee minus a $10 processing charge. Visit the organization's website for the most recent information.
