Run like the viaduct is collapsing behind you! (Note: it won't!) This is the final run on the viaduct before it's torn down, and the first ever run through the new tunnel. 

The Tunnel to Viaduct 8K will head south on the upper deck of the new SR 99 Tunnel and will return on the lower deck of the Viaduct returning north through the Battery Street Tunnel. There will be a water station located at the halfway point of the race course (near 1st Ave S & S King St) with both water and NUUN Hydration located at it. Please note, this course is not flat; both the tunnel and viaduct have moderate elevation gain.

*Final routes subject to change

The Tunnel to Viaduct 8K will begin at the southbound entrance to the new SR 99 Tunnel located at 6th Ave N & Harrison St. Due to the size of the race and size of roadways, the race will begin in waves based on participants estimated finish times. For safety reasons, only participants wearing the official Tunnel to Viaduct 8K bibs will be allowed within the start corrals.

How do I know which corral to start in? Your bib will have a corral designation on it when you receive it and a map of the Seattle Center Grounds on the back that looks like the image below.

Can I start in a different corral? If you’d like to start in a corral ahead of yours, please visit the help desk when collecting your race materials at packet pickup. There will be no corral changes on race day.

I’d like to run with my friends, can I? Yes, you can all run together, but to do so, you will need to start in the last corral of your group. No runners will be allowed in corrals starting before theirs, but you will be allowed to move back corrals.
