We depend on sponsors and volunteers to make events happen. Contact Special Events Coordinator Pam Barrett at or (206) 801-2634 for information about how you can help.

Race Description:

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

The race is not officially timed, but is officially fun.

Food4Kids Weekend Backpack Program: 

Monster Mash Dash 5K is partnering with 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.

Bring your donations to the race! Food4Kids is seeking:

  • Shelf stable, individual-size milk
  • Applesauce pouches
  • Meal replacement bars
  • Granola bars
  • Gift cards to grocery stores
  • Cash


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