Both the full and half marathon start together at Gateway Corporate Center on Interurban Ave in Tukwila, south of downtown Seattle. The course runs through Tukwila and makes its way to the scenic shores of Lake Washington for miles 4 through 9. Full marathoners only split off for 2 miles on the floating Lake Washington Bridge. After 2 miles, both courses meet again and run next to each other on the Interstate 90 Express Lanes. All participants head into downtown Seattle, where the half marathon splits off and finishes downtown outside Qwest Field.

The full marathon continues north onto the Alaskan Way Viaduct/Hwy 99, with views of Elliott Bay, passing the Space Needle and Lake Union as the Alaskan Way Viaduct/Hwy 99 becomes Aurora. Runners will u-turn and head back toward downtown on the highway before finishing outside Qwest Stadium downtown. There are some rolling hills in the latter half of the full marathon course.
