San Juan Island Half

The San Juan Island Half is a point to point half marathon on San Juan Island, Washington. The route begins at South Beach inside San Juan Island National Historical Park and finishes at Jackson Beach just south of Friday Harbor. Runners pass coastal viewpoints with sights of nearby islands, the Olympic Mountains and the Salish Sea.

The course includes about 900 feet of total elevation gain with three main climbs located roughly from miles 0 to 1.6, 3 to 5.3, and 9 to 10.8. Aid stations appear every 2 to 3 miles and are stocked with water, Tailwind Electrolytes and GU gels. The event is cupless, so participants should bring a handheld or a small reusable cup. Free gear check is provided at the start with bag pickup at the finish; participants must bring their own bag.

Logistics note that the island is reached by ferry and a direct ferry from Anacortes takes about 65 minutes. Free shuttles run between downtown Friday Harbor and the start area; the shuttle ride is about 15 to 18 minutes. Participants may be dropped off near the start but parking at the start line is not permitted.

Awards are given to the top three male, female and non-binary finishers by gun time, with age group awards in five-year increments. There is also a kids' race of about 0.4 miles at the finish, and each child receives a finisher medal. Visit the organization's website for the most recent information.
