Cascade Express Marathon and Super Marathon


The Cascade Express Marathon and Super Marathon are both part of the Cascade Super Series races.  Both are run on the same course by the same organization.  The Cascade Express Marathon occurs annually in early September.  The Super Marathon occurs annually in late June.  The Cascade Super Series also sponsors half marathons, endurance runs, an ultra marathon and multi event challenges.

The course is one of the fastest marathon courses in the country! It is also one of the top 20 Boston Qualifier Courses in the country with a BQ rate of over 34 percent! Enjoy 26.2 miles of scenic downhill with a gorgeous view of the Cascades Mountains as you glide down the gravel trail on the point to point course. This is the only marathon course that features jaw dropping views while you run along Keechelus Lake. With 1500 feet of gradual net downhill, the course assures that you will “find your supper fast” on the way to a speedy time, PR, or BQ!  Both marathons are USATF certified.
