Event Overview

The 18th annual Run Scared takes place at Seward Park in Seattle, Washington. This Halloween-themed event benefits Blood Cancer United, an organization formerly known as the Leukemia and Lymphoma Society. Participants can choose between several outdoor race distances or join through a virtual participation option.

Distance Options

The event features the following distances:

  • 10K (6.2 miles)
  • 5K
  • 2 mile walk or run
  • 400 yards (Free Kids Dash)

Participant Information

Registrants receive a long-sleeve race shirt, a surprise finisher's item, and Halloween treats. The event includes a costume contest, a treasure hunt, and an awards ceremony. A packet pickup is available the day before the event at a local running store in West Seattle, as well as on-site on the morning of the races.

Environmental Initiative

Participants have the option to select "Trees not Tees" during registration. Choosing this option directs the cost of the race shirt to an organization that plants a tree in the participant's name. Those who choose this alternative receive a certificate, GPS coordinates, and a photograph of the planted tree. Visit the organization's website for the most recent information.
