Race Description:

The Monster Mash Dash is a family 5K fun run and walk along Shoreline's Interurban Trail. Costumes are encouraged and prizes will be awarded for the best costume in each age group as well as best group costume.

The race will not be officially timed, but will be officially fun.

New this year, the Monster Mash Dash 5K will benefit the Food4Kids Weekend Backpack Program in the Shoreline School District. The Weekend Backpack Program provides supplemental food for the weekends during the school year to students in the Shoreline School District.


The race follows the southern half of the Interurban Trail. Distances are marked for families who would rather complete a shorter distance than the full 5K.
