Vashon Island Ultramarathon & Trail Run
The Vashon Island Ultramarathon & Trail Run is a USATF sanctioned trail event held on June 5, 2027 in Vashon Island, WA. The event is organized by a volunteer, non-profit 501(c)(3) and limits field size to 200 participants to reduce environmental impact and maintain safety. Proceeds support island youth athletics.
Three looped race options use the same start/finish at the Gateway Trail system near SW 178th and 103rd SW:
- 50K three loops of the course
- 20 Miler two loops of the course
- 10 Miler one loop of the course
The course runs primarily on single track and double track park trails with some dirt roads, gravel driveways, grass shoulders and short paved sections. Elevation change is about 770 feet per loop. Trails include roots, downed logs and sharp changes in elevation; runners should remain alert. The route passes on both public and private land and is not closed to the public, so encounters with equestrians, pedestrians and bicyclists are possible.
Aid stations are located at about miles 6 and 10; 50K runners pass each aid station three times. Stations offer water, soda, carb drink, snacks, fruit, gels and drop bag support at base camp and selected aid points. Porta-potties are available at multiple locations on the course. A course map and GPX file are emailed to entrants before the race. The event follows USATF Safe Sport and MAAPP requirements. Visit the organization's website for the most recent information.
