Race Info
The Lake Washington Half Marathon is a loop course that starts and finishes at Juanita Beach Park in Kirkland, Washington. Runners follow the Lake Washington shoreline and return through Kirkland neighborhoods, and the usual route has used the Cross Kirkland Corridor trail. The race is held on a Saturday in the fall, has a 3.5-hour time limit and sends runners off in four waves two minutes apart. The course was USATF certified (WA16027RMB), but a 2026 detour around construction on the trail ended that certification for this edition.
