Seattle Marathon

Course on the Homer M. Hadley Memorial Bridge in 2013

A former course began on 5th Avenue N. between Harrison and Mercer Streets in front of the Museum of Pop Culture on the eastern edge of the Seattle Center campus, followed 5th Avenue through Downtown and the International District to Interstate 90, followed I-90 across Lake Washington to Mercer Island, turned around and headed back across the Homer M. Hadley Memorial Bridge to the shoreline, followed Lake Washington Boulevard S. to Seward Park, looped Bailey Peninsula, and followed Lake Washington Boulevard S. back up the shoreline to McGilvra Boulevard E. in Madison Park. From there, the course followed E. Madison Street southwest to the southern entrance of the Washington Park Arboretum, turning north on Lake Washington Boulevard E. to E. Interlaken Boulevard. The course followed Interlaken northwest out of the Arboretum and through Interlaken Park, then west across Interstate 5 to Boylston Avenue E. Heading south, it followed Boylston back under the freeway, where it becomes Lakeview Boulevard E., then followed Lakeview south, once again over the interstate, to Eastlake Avenue E. The course turned west on Republican Street through Cascade to Dexter Avenue N., where it jogged north one block to Mercer Street, then turned south on 4th Avenue N. and finished within Memorial Stadium in Seattle Center.[10]

The marathon course begins on 5th Avenue N and Harrison Street near the Space Needle, and ends in the nearby Memorial Stadium.[11]

The course first heads southwest into Downtown Seattle before heading north via Interstate 5 and crossing the Lake Washington Ship Canal via Ship Canal Bridge.[11] Runners then head up to NE 103rd Street (just past Matthews Beach Park) and back via the Burke-Gilman Trail.[11] The marathon continues west largely on the trail until hitting a turnaround point near 8th Avenue NW, and then heads back south across Lake Union via the Aurora Bridge to finish in Memorial Stadium.[11]
