Chilly start, adjust pace wisely

Runners will face a cool start at 37°F, gradually rising to 43°F. With a light 5 mph wind and high humidity at 82%, runners should consider pacing conservatively, especially during the early climbs from miles 1 to 3 and 9 to 11. The chance of light rain may also necessitate a throwaway layer during pre-race; hydration will be crucial given the humidity.

Race Info

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. Source
