About the Seattle Half Marathon
Seattle's half has its own start time and course within the Thanksgiving weekend event. The organizer has also announced the next edition, giving Marathon Scout two confirmed annual dates.
Course
The half starts near Fifth Avenue and Harrison Street by Seattle Center and finishes at Pier 66. Urban grades and late-November weather can make the route more demanding than its distance alone.
Race-day weather
Late November in Seattle is typically cool and wet, with wind possible near Elliott Bay. Rain-ready layers and traction awareness are sensible even if the forecast looks mild.
