Vashon Island Ultramarathon & Trail Run
This trail race takes place on Vashon Island, Washington on June 5, 2027. It offers looped courses that share a common start and finish at the Gateway Trail system near SW 178th and 103rd SW.
Distances:
- 50K three loops of the course
- 20 Mile two loops of the course
- 10 Mile one loop of the course
The course runs primarily on single track and double track park trails with short sections of dirt road, gravel driveways, grass shoulders and paved road. Each loop has about 770 feet of elevation change and includes short steep hills, roots, downed logs and quick turns. The route passes through public and private land; permits are held but trails are not closed to other users, so runners should expect to encounter equestrians, pedestrians and bicyclists.
Aid stations are located around mile 6 and mile 10; 50K runners will pass them three times. Typical aid station provisions include water, sodas, carb fluids, salted snacks, fruit, sandwiches, gels, stroopwafels and other packaged items. There is a base camp at the start/finish with drop bag space and periodic access to drop bags at the Land Trust Aid Station.
The event is USATF sanctioned and follows Safe Sport and MAAPP requirements. Participant numbers are limited to 200. The event operates as a volunteer-run, nonprofit fundraiser for island youth athletics. Organizers do not offer refunds; entry transfers are permitted until the stated cut-off.
