Whidbey Island Marathon, Half Marathon, 10K & 5K

Sunday, April 23, 2023 • Oak Harbor, WACourse Map

Washington State’s Whidbey Island is the setting for the Whidbey Island Marathon, Half Marathon, 10K, 5K & 1K, which takes place each year on the second-longest island in the continental United States, and is set for its 15th annual running this year.

Accessible by vehicle from the mainland (the island lies just north of Seattle in Washington’s Puget Sound, Whidbey Island is a treasure of scenic natural beauty — with ample views of the nearby ocean, peaceful backroads through the island’s farmland areas, and the snow-capped peaks of the nearby Olympic and Cascade mountain ranges.

Runners will get to see many of the sights and sounds available here during the race, as much of the course takes runners along the waterfront.

The course for the half marathon starts near the finish line of the full 26.2-mile marathon, at the Bayshore Drive Waterfront in beautiful downtown Oak Harbor.

From there, the point-to-point course winds through paved city streets, country roads and trails, taking runners and walkers (the race is open to both) along Bayshore Drive, through Windjammer Park, ultimately southward toward Windjammer Park on the middle portion of the island near Penn Cove.

For most of the race, the half marathon offers gently rolling hills, with the most significant changes in elevation occurring between the quarter-point and half-way point in the race (overall, the half marathon experiences a net rise of about 150 feet in elevation).

    Hello, I registered myself and daughter for the 5 K this Sunday – but we cannot attend. I am recovering from the flu and she is moving. Is there any chance of a refund? Thank you.
