Event Description


From its humble beginnings in 1970 when a group of friends from the University of Washington decided to hold their own marathon, the Seattle Marathon Family of Events has grown into one of the largest combination marathon/half marathon in the Northwest. That first marathon sported 38 runners. This year, 10,000 participants are expected for the marathon and half marathon walking and running events. Join us the Sunday after Thanksgiving for Seattle's Original Hometown Marathon.


In order to make sure all participants have time to reach mile 5 and pass the I-5 express lanes by 9:15 we have moved up the start times to the following:

Full Marathon Run / Walk - 7:00 am
Half Marathon Run / Walk - 7:30 am


All participants must be off the I-5 Express Lanes by 9:15am to that it may open to traffic at 9:30am. This allows Half Marathoners starting at 7:30am a 21 minute pace to reach mile 5 and Full Marathoners starting at 7am a 27 minute pace to reach mile 5. 


All event routes will be opened to regular vehicular traffic at 2:15pm. This allows for a seven-hour Marathon Walk finish and a six-hour Marathon Run finish. There will be limited on-course aid stations, Course Marshals and police support after the course closes. Participants may continue along the course after the official closure by obeying all standard traffic control devices. Finish Line staff and essential services will remain until every athlete has completed the event. 


Each mile-marker will be clearly labeled on the race courses.  Split times will be called at each marker (as permitted by the number of volunteers).  Half marathon split times will be electronically recorded and available in marathon results.


Water/Aid stations are approximately every two miles. There are 14 Water/Aid Stations on the full marathon course and 7 on the half marathon course. Refer to the course map for locations.

Talking Rain water and Gatorade Endurance Formula sports drink will be available at each station, in addition to basic medical items and Honey Bucket portable toilets. GU will be available at water stations at mile 5.4 for the full and half marathons and miles 9.7. 14.25 and 18.5 for the full marathon. Each water / aid station will remain supplied until the last participant has passed.

TalkingRain is the official water sponsor of the Amica Insurance Seattle Marathon 2019. For more information about TalkingRain water, please visit

Lemon-Lime Gatorade Endurance Formula will be available on course at all aid stations. Endurance Formula has nearly two times the sodium and three times the potassium of traditional Gatorade. Newly reformulated, it now contains no artificial flavors or sweeteners and has a new, lighter flavor. Learn more about the Gatorade Endurance line of products at

Gu Energy Gel will be available in the following flavors: Salted Caramel, Vanilla Bean, Chocolate Outrage, Tri Berry and Strawberry Banana.
