Hosted by Orca Running on the Alki waterfront, the course serves up skyline and Puget Sound views on a USATF-certified half marathon route with gentle grades. Start at Lincoln Park, cruise the shoreline with a couple of short out-and-backs, and finish at Don Armeni Boat Launch—ideal for first-timers and PR-chasers alike. In addition to the in-person options, you can take on the Blowhole Challenge by racing both days or choose a Virtual Half Marathon if you’re running from afar.
