2015 Series


Ft. Steilacoom Park, Lakewood, WA

This is a series of three races at Ft. Steilacoom Park. All races will be on identical courses so you can track your fitness level over time. If you’re new to duathlons, it involves a running leg and a biking leg. It’s a lot like a triathlon except it’s all on trails and there’s no swimming involved (see Wikipedia definition). Trail Duathlons in particular are great for those of you that mountain/cyclocross bike and trail run or have a friend who wants to team up for a race.

Race #1 – January 4: Cancelled, due to low registrations.
Race #2 – January 25: Cancelled, due to low registrations.
Race #3 – February 8

Cancellation Policy

This is a winter race series. Come prepared for cold and wet conditions in addition to inclement weather. Races will occur unless the weather makes racing unsafe due to lightning or high winds, the amount of snow on the ground makes it impossible to ride, or the park is closed. In the event that a race must be cancelled, the race will be rescheduled for the following weekend and no refunds will be given.


Up to 2 weeks before the race, 50% refund.  Please note that we incur costs for insurance, permit fees, food, swag, printing, safety services, and planning for each registered racer. We are a very small company, and we have a hard time absorbing cancellations at the last minute.

Leave No Trace

We are dedicated to the responsible enjoyment and active stewardship of the outdoors, and we encourage you to “leave no trace behind” by taking all trash with you. The park rangers always appreciates it when racers follow the marked course and keep the trails clean, and they are much more likely to grant permission for us to put on races at the same location if the trails are kept in good condition.
