10 mile, 20 mile, 50k:

Welcome back runners for the 16th year of trail running on Vashon Island! This year we introduce Team Competitions! Three team members add up their finish times to find out how they compare – three categories: Female, Male and Mixed. Teams must have a Team Captain to add their team’s times and report to the Finish Tent

All races will embark from the same start line/finish line at the Gateway Trail system near SW 178th and 103rd SW.. Porta Potties are at 0, .5, 1.4 and 6 miles. If “going” in the woods, please step off the trail and be discrete. A map/course GPX will be emailed to entrants a week prior to the event as the course passes through private property, and we want to keep traffic down on those portions to keep friendly relations. Otherwise, go on to Strava and look up the course from past winners/runners. The first 1/4 mile will be dirt road, then taking runners into Island Center Forest’s Gateway Trail system.

Runners will get their first exposure to the Gateway Trail – one of the newest additions to ICF’s trail system. Runners will travel around in a general clockwise direction, first heading to the 188th lot, onto the 188th Trail, Valley of the Firs, Grinder, Mikes and Craigs, middle and north trails, borrow pit, to AS1 at Fisher Pond, around the pond to 115th, then back into the ICF and around Mukai Pond and the perimeter of Dragons Head Cider Farm. There, you only have a mile to go to the finish/AS2/turnaround. As usual the course will be clearly marked – but runners should remain alert just the same. The course will basically travel the interior and perimeter of the park, ending up back at the Start/Finish, where the 10 milers will finish and the 50k runners will head back out on Gateway Trail for two more loops.

Aid stations will be located at miles 6 and 10. 50k runners will pass each aid station 3 times.

There are no refunds (contact the RD about roll-overs, which are only granted for reasons outside the control of the runner)
There will be day-of-race registration, 50k registrants first, then 10 and 20 mile registrants at 8:30 after 50k’ers leave.

Camping on Friday night is an option. Please email us to confirm you are planning to camp prior to arriving. Camping will be in the big grass field at the start/finish, near SW 178th and 103rd SW, with porta-potties and water in jugs. Thank you!
