The Cascade Express Marathon course is one of the fastest in the country. The low starting elevation of 2,550' and gentle decent makes the courses great for fast times. It is the perfect race to set a PR, snag a BQ and have a great time. Don't let "trail" in the description deter you. The courses are smooth and runnable much like road events. You can expect fast feet with 1,500' of total elevation loss at a consistent grade.
The Cascade Express Marathon course starts at Snoqualmie Pass, makes a 5 mile out and back on the Iron Horse trail before entering the 2.4 mile Snoqualmie Tunnel. The first 7.5 miles of the course are relatively flat with minimal elevation gain or loss. The course becomes downhill after running through the tunnel to the finish at Rattlesnake Lake Park.
The Super Marathon is run on the same course in June.
