Race Overview

Grand Ridge Park is an incredible setting to finish off this year. Since 2000, the Washington Trails Association has been hard at work developing over seven miles of connected trail from old logging roads and user-built paths. It has all come together to create a beautiful system of trails that are ideal for running, hiking and biking.
