The Cougar Mountain Trail Series is successfully run with the assistance of our many and cherished volunteers. If you’ve ever run a series race, or you just want to help out in the local running community, we would love to have your assistance at our next race!

In terms of scheduling, the Cougar Series races are traditionally held every 2nd Saturday during the months of May through August, in addition to our fall races which are held on the last Sunday in October.

  • Jobs include directing parking, registration and packet pick-up, working aid stations, finish line greeting, course marking, course monitors, course sweeping, and clean up.
  • If you’re racing, you can still volunteer! Some positions are only needed pre or post-race.
  • The average time commitment is usually only two to four hours.

If you would like to volunteer for a specific date, or you’re simply open to helping out sometime in the future, please contact We appreciate all help we can get to keep the Cougar Mountain Series running as one of the best trail race series in the entire country!

Can’t make it on race day? Seattle Running Club also hosts a trail work party the Saturday¬†before each summer race to help keep Cougar Mountain’s trails looking great. If you’re interested in joining for this, please contact
