Gulch Countdown : Last Person Standing trail race

Gulch Countdown is a Last Person Standing trail race held on June 13, 2026, in Japanese Gulch in Mukilteo, WA. The course is a loop of 2.18 miles through forest terrain with ferns, moss-draped trees, and large cedars. The rolling hills provide a mountain-like feel close to town.

The event is timed in a nontraditional format: runners complete repeated loops and must finish each loop within a progressively shorter cutoff. The first loop has a 32 minute cutoff; qualifying finishers regroup and start the next loop in the opposite direction with a reduced cutoff. After 12 loops (a marathon distance) loop cutoffs reduce by 30 seconds until only one runner remains as the Last Person Standing. There is also a recognition and competition for the fastest lap of the day for men and for women.

A full aid station will be provided on course. Five dollars from each registration is allocated to trail improvements in Japanese Gulch. The event is organized by the local running club Japanese Gulch Runners, which began in January 2017 to build a welcoming trail running community in Snohomish County.

Registration closes June 11. Visit the organization's website for the most recent information.
