MARATHON

A BOSTON QUALIFIER
(Click here for Boston qualifying times)

  • Marathon runners park at Hyak Sno-Park and take a short shuttle ride to the start at Crystal Springs Sno Park.

  • The course begins and follows the scenic Palouse to Cascades Trail toward Snoqualmie Pass. Runners reach the Snoqualmie Tunnel about mile 13, so a headlamp or flashlight is required. A drop bin is provided after the tunnel so your light can be transported to the finish (please label your gear).

  • After returning to Hyak, the course continues along the rail trail toward the finish at Garcia in North Bend.

  • The first half of the marathon is mostly flat and runnable, followed by a long, gradual downhill for the final 13 miles— a profile designed for strong negative splits and fast finishes.

  • Total downhill: approximately 1,300 feet

  • The surface is a smooth, hard-packed gravel rail trail that is gentle on the legs and ideal for chasing PRs and Boston Qualifiers.

  • Post-race shuttles return runners to Hyak parking. There is a one mile walk from the finish line to the bus pickup area. It is a nice cool down, recovery walk and really no way around it other than down
