Orcas Island 100 Miler : Olga, WA

The Orcas Island 100 Miler is a trail running event on Sx’wálex, also known as Orcas Island, in Olga, Washington. The course is a 100 mile distance run as four 25 mile loops on mostly single track trails with varied surfaces. The cumulative elevation gain is approximately 26,000 ft. Weather can vary from rain to snow to sun.

Aid support includes about 15 aid stations and four full aid stations used on each 25 mile loop. Aid stations provide water, electrolyte drink, snacks, hot options and station-specific foods; runners may use drop bags. Crews are allowed at most aid stations with some restrictions on the first loop. Pacers are permitted starting at mile 25 and must follow rules about not carrying gear or providing aid except at aid stations.

Entrants must meet a qualifying standard from recent long trail events. Participants are required to complete one day of trail work (6 to 8 hours) in the 12 months prior or submit a minimum donation with proof. There is a 36 hour overall cutoff and additional aid station cutoffs. All finishers receive a belt buckle and all entrants receive a race hoodie. An optional Tower Club award is available for runners who climb the Mt Constitution tower on each loop.

Arriving by ferry is necessary; vehicle reservations may be required. Lodging options include on-site Camp Moran bunkhouses with basic accommodations. Visit the organization's website for the most recent information.
