Cool and damp, hilly challenges ahead

Runners will face a temperature range from 52°F at the gun to 60°F by mid-race, with high humidity at 80%. Light rain is expected, but intensity will be minimal. The hilly course will present challenges, especially during climbs from miles 1-3 and 9-11, where pacing adjustments may be necessary. Runners should consider a conservative start to manage the elevation gains and potential fatigue.

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
