Whidbey Island is the perfect island weekend getaway where you can leave the city behind. Just north of Seattle, nestled up in Washington State’s Puget Sound is Whidbey Island. As a destination vacation playground for many, the island provides a vehicle-accessible getaway from the busier mainland. Providing picturesque ocean views and tranquil farmland, the full marathon and half marathon courses promise to be scenic from country back roads to waterfront coastlines, snow-capped mountains, and rolling hills. It's the perfect race for your weekend adventures. Source
