Significant Half Marathons Around the Country to Consider

Seattle Marathon

The UW Medicine Seattle Marathon and Half Marathon is Seattle’s original hometown marathon and the oldest marathon in the Pacific Northwest. Starting in the shadow of the Space Needle, the course showcases the pristine Pacific Northwest before looping back to finish on the AstroTurf at Memorial Stadium. And though avoiding hills in Seattle is like avoiding sand in the desert, Emerald City gems like Lake Union, Lake Washington, and the University of Washington help to temper the route’s inevitable ups and downs.

The Eugene Marathon is a beloved annual event that draws runners from all over the world to the beautiful city of Eugene, Oregon. With a rich history and a reputation for being one of the most scenic and challenging races in the Pacific Northwest, the Eugene Marathon is a must-run for any serious runner.
