Lessons Learned from Race Reports

  • This course has changed each year in the previous few years, so it’s a hard to look at previous race results and race reports, but typically the courses have been hilly with plenty of aid and course organization.
  • Always be ready for hills with races starting and finishing in downtown Seattle. Courses have typically been hillier than people expect in the past.
  • Some parking around Seattle Center, but it’s also within walking distance of a lot of downtown hotels, and the Monorail runs to and from downtown (Westlake Center) to Seattle Center (check if it’s running that early)
  • If traveling for the race, consider booking a hotel within a half mile of Seattle Center so you can just walk to/from the race
  • Fairly hilly course for a road full and half marathon, with the biggest hill later in the race for the half marathon and hills throughout for the full, with bridge crossings.
  • Elevation profile for the full marathon isn’t entirely accurate because of bridge crossings
  • Both the Marathon and Half Marathon start at the same time and share the same course for awhile, so expect to be running around quite a few people who are continuing onwards and pay attention to the split point.
  • With it being mid-June in Seattle, the weather could still be anything from 50’s and rainy to 60’s and sunshine, so be prepared for wet or warm weather
