North Bend is a mecca for downhill marathons in the United States.  It has multiple opportunities for Boston qualifying over a scenic gentle downhill course.   The exact start and stop locations depend on the specific marathon and distance (full or half).  

The start location is around Snoqualmie Pass.  The race course is the incredibly scenic gentle downhill slope of the Palouse to Cascades Trail.  The elevation ranges from 2500 feet down to 400 so you don’t need to worry about altitude issues.  Located in the mountains of Washington State, it’s unlikely to be too hot.  But even on the slight chance it is, there is much shade from the forests along the way.  You’ll also get some amazing views of the the Cascade Mountains and the South Fork Snoqualmie River valley along the way.  There are also some waterfalls and several long trestle bridges as the trail used to be a railroad.
